Reagent for measuring cadmium and preparing method thereof

Abstract

The invention relates to a detecting technique of heavy metal cadmium, in particular to a reagent for rapidly detecting the cadmium and a preparation method thereof. The reagent consists of a reagent A and a reagent B, wherein, by weight proportion, the reagent A consists of 50-200 parts of visualization reagent, 100-1200 parts of acidity regulating reagent and 100-800 parts of sensitizing reagent; and the reagent B consists of 20-150 parts of buffering agent, 10-80 parts of masking reagent 1 and 30-100 parts of masking reagent 2. By adopting the invention, the analysis procedures can be simplified, such as operations of weighting, solution allocation, and the like, can be omitted, the advantages of convenience and the rapidness can be brought, the personal errors can be reduced, and the accurate result can be obtained by the operation by persons who are not analyst. The validity period of the reagent A is more than six mouths after being tightly stored at normal temperature; and the reagent B belongs to solid powder capsules, which avoids the instability, and the like, of the liquid reagent, thereby the validity period is more than eight mouths after being tightly stored at the normal temperature.

Description

technical field

[0001] The invention relates to a detection technology for heavy metal cadmium, in particular to a reagent for rapid detection of cadmium and a preparation method thereof. Background technique

[0002] Since the discovery of cadmium in the early 20th century, the output of cadmium has increased year by year. A considerable amount of cadmium is discharged into the environment through waste gas, waste water, and waste residue, causing pollution. After the environment is polluted by cadmium, cadmium can be enriched in organisms and enter the human body through the food chain, causing chronic poisoning. Cadmium poisoning mainly manifests as osteoporosis, decalcification, and osteomalacia. Chronic cadmium poisoning can cause mild hypochromic anemia; acute cadmium poisoning can cause pulmonary edema and emphysema. Cadmium is a highly suspected carcinogen that may cause prostate and bronchial cancer.
