[Comparative testing of methods for determining arsenic in food products]. 1979

S Velev, and D Grigorova

Two methods for arsenic determination on food products were tested, namely: with silver diethylthiourea and after molybdenum blue as presented in AOAC--1975. Better repeatability of results was observed when the method with silver diethylthiourea was used (94--96%). It is recommended that this method be included in BSS. In order to improve the repeatability of results in case the molybdenum blue method is used it is recommended that the contruction of the standard curve follows the entire analytical course post mineralization.

D001151	Arsenic	A shiny gray element with atomic symbol As, atomic number 33, and atomic weight 75. It occurs throughout the universe, mostly in the form of metallic arsenides. Most forms are toxic.
