Uranium Detection Kit for Domestic Water (UDK)

Uranium Detection Kit for Domestic Water (UDK)

Overview

Uranium is a ubiquitous element in rock, soil, and water. The most stable form of uranium in water is the hexavalent uranyl ion (UO22+). If swallowed, it can deposit in organs such as lungs, bones, kidneys and liver thereby causing several health problems such as renal failure and cancer. Due to high mobility and toxicity of uranium, the World Health Organization (WHO) and Atomic Energy Regulatory Board (AERB), India, set the maximum allowed concentration limit of U in drinking water as 30 and 60 ppb respectively. Therefore the detection and determination of uranium at trace levels is necessary to determine the suitability of water for human consumption.

A simple and rapid visual colorimetric method has been developed for the detection of the presence of uranium in domestic water. Depending on the uranium concentration, the development of the colour change takes place instantaneously; thus water samples can be immediately categorized as safe, permissible or toxic for drinking with respect to uranium. The developed kit can be used with very minimal instructions, both in domestic and community level monitoring of uranium in domestic water.

Quick View Leaflet

Uranium is a ubiquitous element in rock, soil, and water. Uranium concentrations in natural ground water can be more than several hundreds of ppb as a result of leaching from natural deposits, release in mill tailings, emissions from the nuclear industry, the combustion of coal and other fuels and the use of phosphate fertilizers that contain uranium. The most stable form of uranium in water is hexavalent uranyl ion (UO22+). If swallowed, it can be held on organs such as lung, bone, kidneys and liver thereby causing several health problems such as renal failure and cancer. Due to high mobility and toxicity of uranium, the World Health Organization (WHO) and Atomic Energy Regulatory Board (AERB), India, set the maximum allowed concentration limit of U in drinking water as 30 and 60 ppb respectively.

Therefore the detection/estimation of uranium at trace levels is necessary to determine the suitability of water for human consumption.

A simple and rapid visual colorimetric method has been developed for the detection of the presence of uranium in domestic water. Depending on uranium concentration, on using this kit, a color change takes place instantaneously, enabling the detection of the presence of uranium below/at/above permissible levels.

SALIENT FEATURES

  • Onsite detection and instantaneous results.

  • Low investment on infrastructure for preparing the kits.

  • Low cost and easy availability of the reagents.

  • Kit can be used by any individual, with minimal instructions.

APPLICATIONS

  • Uranium Detection Kit is useful for testing domestic water samples in uranium affected areas.

  • Highly suitable for the periodic monitoring of uranium contamination in water.

  • With very minimal instructions, the method can be used by any individual, both at domestic and community level monitoring of uranium in ground waters.

Detail Technical Brochure

Uranium is a ubiquitous element in rock, soil, and water. Uranium concentrations in natural ground water can be more than several hundreds of ppb as a result of leaching from natural deposits, release in mill tailings and other anthropogenic activities, the combustion of coal and other fuels and the use of phosphate fertilizers that contain uranium. The most stable form of uranium in water is the hexavalent uranyl ion (UO22+). If swallowed, it can accumulate in organs such as lung, bone, kidneys and liver thereby causing several health problems such as renal failure and cancer. Due to high mobility and toxicity of uranium, the World Health Organization (WHO) and Atomic Energy Regulatory Board (AERB), India, set the maximum allowed concentration limit of U in drinking water as 30 and 60 ppb respectively. Therefore the detection/determination of uranium at trace levels is necessary to ensure the suitability of water for consumption.

A simple and rapid visual colorimetric method has been developed for the detection of the presence of uranium below or above the maximum permitted contamination levels in domestic water. Depending on the uranium concentration, by using this kit, a colour change takes place instantaneously, thus enabling the detection of the presence of uranium below/at/above permissible levels.

APPLICATION

  • The Uranium Detection Kit is useful for testing domestic water samples in uranium affected areas.
  • It is also highly suitable for the periodic monitoring of uranium contamination in water.
  • With very minimal instructions, the method can be used by any individual both at domestic and community level monitoring of uranium in ground waters.

ADVANTAGES

Simplicity :
  • The method uses very low concentrations of reagents which not only make the procedure inexpensive but it is also in accordance with the Green Chemistry recommendations. There is no need for any costly equipment either. In addition, the testing procedure is very simple and rapid.

Instantaneous color development :
  • The color development takes place immediately. A test can be completed within 1-2 minutes. Instant color development and good color contrast at the three concentration levels of uranium (below/at/above permissible levels) are the main features of this method.

Stability of Reagent :
  • Stability of reagent is one of the major requirements for any field method. No deterioration in the quality of the developed reagents was observed during their storage for over six months under ambient conditions.

Validation :
  • The method has been extensively tested for visual detection of uranium in spiked and actual ground water samples. The results derived from visual detection for below/at/above permissible levels of uranium were found to be in very good agreement with those obtained using standard methods such as laser fluorimetry and ICP-MS.

Semi quantitative estimation :
  • If uranium concentration is more than 100 ppb, its concentration can be estimated in semi-quantitative way by appropriate dilutions.

Suitable for spectrophotometry :
  • Quantitative analysis by a spectrophotometer can be carried out after dissolution of the precipitate followed by measuring absorbance at 650 nm within a calibration range of 10 to 100 ppb.

Interferences :
  • The developed method is free from interferences from cations (except thorium) and anions at levels which are normally present in ground waters. It can be applied even in the presence of high levels (~1700 ppm) of total dissolved solids (TDS).

WORKING PRINCIPLE

The method is based on the formation of a uranium complex that gives concentration dependent coloration. A surfactant is utilized for the coagulation of the uranium complex for its easy detection and identification. Depending on the uranium concentration, the development of the color change takes place instantaneously, thus enabling the detection of the presence of uranium below/at/above the permissible levels. The Uranium

  1. UVDK reagent-1 : 1 bottle (100 mL)
  2. UVDK reagent-2 : 1 bottle (100 mL)
  3. 100 mL standard flasks : 4 Nos.
  4. Color Chart : 1 No.
