Spectrophotometric Determination of Arsenic in Organs of Human Being With Arsenic-Antimony-Molybdenum- Rhodamine B Molybdogermanic Blue System

摘要

Chemists often use AsMo blue spectrophotometry and the method of Silver Diethyl Dithiocarbamate to determine Arsenic. The authors of this paper designed a new method to determine Arsenic. Ascorbic acid reduced molybdogermine aeid of AsS-bMo to molybdogermanic blue and then formedion-associate complex of molybdogermanic blue-rhodamine B in the presence of mixture of acetone and butanone. This new method is easy to operate、 high sensitive, and is really a practical satisfactory method.
