A reagent for measuring lead content in urine and its rapid detection method

Abstract

The invention discloses a reagent for measuring the lead content in urine and a rapid detection method thereof, which can effectively solve the problem that urine lead detection means are cumbersome and costly, so that it is sometimes impossible to test urine lead. The technical solution is, yes 0.2ml of sodium thiocyanate solution with a mass fraction of 15% to 25%, 0.2ml of a citric acid solution with a mass fraction of 0.01% to 0.05%, 0.05ml of a strong acid with a mass fraction of 0.025M to 0.5M and a mass fraction of 0.1% to 0.5 % crystal violet solution 0.05ml, the reagent of the present invention is convenient to use, the result is accurate and intuitive, the operation is simple and fast, the color development is obvious, the sensitivity is high, and no special equipment is needed. It is suitable for hospitals and health centers (institutions) at all levels to guide various groups of people to detect urine lead content, is easy to popularize and apply, and has outstanding clinical use value for preventing urinary lead poisoning.

Description

Technical field [0001] The invention relates to a reagent for measuring the amount of lead in urine and a rapid detection method thereof related to medical applications. Background technique [0002] Lead is a kind of heavy metal with a wide range of uses and a non-essential element for the human body. With the development of industrial and agricultural production, lead and its compounds are increasingly polluting the environment and food. Lead and its compounds enter the body through the respiratory tract, digestive tract, skin and mucous membranes, most of which are stored in bones, and a small part is distributed to various tissues and organs of the body with blood circulation, and combines with sulfhydryl groups in proteins, enzymes and amino acids. This seriously affects the functions of the human nervous system, hematopoietic system, digestive system and kidneys. The main groups harmed by lead pollution are children, pregnant women, police, and lead workers. Among the no...
