【摘要】 提出了一种检测有机磷类化合物的新方法。将单磺酸四苯基卟啉（TPPS₁）的光谱特异性与植物酯酶的高效催化效率相结合,以甲基膦酸二甲酯（DMMP）为检测对象,可在几分钟内检测到浓度低至9×10^-11M的DMMP。因此,基于该检测方法的传感器可实现对有机磷类化合物的有效检测,对环境及食品安全评价、监控有机磷污染等方面具有重要意义。更多还原

【Abstract】 A novel method for detecting organophosphate compounds,which is based on unique spectrophotometric characteristics of monosulfonate tetraphenyl porphyrin(TPPS₁ and the high Catalytic efficiency of plant-esterase,was reported in this study.The studies are carded out using dimethyl methyl-phosphonate（DMMP）.DMMP concentrations as low as 9×10^-11 M have been detected in a few minutes. So this research also provides a practical and sensitive method to optical sensors.The sensor’s potential ability to detect very low levels of compounds is helpful,precluding the need for dangerous levels of the agent to be used in testing.更多还原
