| Abstract: | Solvent flotation spectrophotometry was used here to determinate ppb grade arsenic. In the test procedure, arsenomolybdenum heteropolyblue and crystyl violet system was used as flotant, toluene and benzol mixture as solvent. The spectrophotometric measurement is at 576 nm. The above method could be used to determinate trace As in inorganic and organic samples. |
