Abstract Phase solubility analysis (PSA) was applied to the determination of azinphos-ethyl and - methyl standards. The presence of 0.5% purity was detected by the method. A linear cumulative effect was obtained when known amounts of two impurities were added to standards of both organophosphate materials which were then analyzed by the phase solubility method. 相似文献
