摘要
Abstract
A new method for the simultaneous determination of phosphate and arsenate in water combined low pressure ion chromatography and arsenoantimonomolybedenum blue method detected by spectrophotometry was described, which use Low Pressure ion Chromatography column and the select the mixture of 1.4 mmol/L sodium carbonate and 0.2 mmol/L sodium bicarbonate as the eluent. Under the optimized conditions, the calibration curves of Phosphate and Arsenate ions were linear in the range of 5 ~200 μg·L-1 as P and 5 ~ 150 μg·L-1as As, with a limit of detection of 1. 54 μg·L-1 and 3. 26μg·L-1, respectively. Relative standard deviations (RSD) for Phosphate and Arsenate were less than 2. 14% and 3. 32% , respectively. Analysis Environmental water has been analyzed by this method, recovery ranges of Phosphate and Arsenate in the samples are 97. 89% - 102. 5% and 100. 52% - 106. 79%.关键词
