A turbidimetric test for rapid quantification of As(III) (detection limit of 3 mg/L, quantification range of 10–100 mg/L) in liquid growth medium was developed for assessing and monitoring microbial As(III)-oxidizing and As(V)-reducing activities. This test is based on As(III) chelation with pyrrolidine dithiocarbamate followed by spectrometric measurement of absorbance, and was validated by comparison with AAS quantification of As after As(III)/As(V) separation.

快速，简单的As（III）定量使用浊度法监测微生物砷的生物转化。

为了评估和监测微生物中As（III）的氧化和As（III）的含量，开发了一种比浊法，用于快速定量液体生长培养基中的As（III）（检出限为3 mg / L，定量范围为10-100 mg / L）。五）减少活动。该测试基于吡咯烷二硫代氨基甲酸酯与As（III）的螯合，然后进行吸光度的光谱测定，并且通过与As（III）/ As（V）分离后的AAS定量比较进行了验证。
