测汞仪法在强酸性介质中,用二氯化锡作还原剂测定水中的汞,但由于测汞仪的稳定性差,仪器成本高,操作不便,故该法未能广泛应用。而用汞与双硫腙形成络合物比色法的测定方法,由于灵敏度低,操作繁琐,所使用试剂毒性大,也多有不便。本实验使用VA-90气态原子化装置与原子吸收分光光
Mercury analyzer method In strong acidic medium, the use of tin dichloride as a reducing agent for the determination of mercury in water, but because of the poor stability of mercury detector, the instrument cost is high, the operation inconvenience, so the law can not be widely used. However, the determination method of the colorimetric method for the formation of complex with mercury and dithizone has many inconveniences because of its low sensitivity, cumbersome operation and reagent toxicity. The experiment used VA-90 gaseous atomization device and atomic absorption spectroscopy
