SIMULTANEOUS SPECTROPHOTOMETRIC DETERMINATION OF ARSENIC AND ANTIMONY

Qiu Sunqing;Wang Bingwu Changchun Institute of Applied Chemistry, Academia Sinica  
A simnltaneous spectrophoto metric method for Sb and As determination has been.established. SbH_3 and AsH_3, produced by addition of a KBH_4 tablet to Sb~(3+) and As~(3+)in tartaric solution,were absorbed by a 95% alcohol solution of Fe~(3+)-1,10 phenathrolineand a mixed solution of AgNO_3, PVA and alcohol. The absorbances were measured at 400nmfor As and 510nm for Sb. Tolerance levels of various ions were given. The detection limitswere 0.09ppm (3 s) for Sb and 0.05ppm (3 s) for As. The method is simple, rapid, andsensitive.
