摘要：

A sensitive and selective method is developed for the spectrophotometric determination of trace amounts of arsenic. The method is based on the reaction of arsenate with acidified molybdate and vanadate to form molybdovanadoarserate complex which then interacts with cationic dye, rhodamine B to form an ion-pair.
