【摘要】 本文对十几种有机氯化物进行了光解试验,结果表明;应用1000W 的高压汞灯,除饱和长直链烷烃有机氯化物外(c≥3),其它有机氯化物在 pH=10～12的条件下,辐射30分钟,均能完全光解.回收率在95～101%之间,相对标准偏差小于4%,对于长链有机氯化物通过稀释或延长时间也可以达到完全光解的程度.光解后形成的氯离子,可用氯离子选择电极或分光光度法测定。本法可用于天然水和环境污水中有机氯的测定,较一般通用的方法简便、快速。更多还原

【Abstract】 In this paper,1000W high-pressure mercury lamp is used as a source of ultraviolet radia- tion.the effects of concentration acid,temperature and oxidant are studied.We observed that un- der the condition of pH about 10,nearly all types of organic chloro-compounds can be quantitative- ly decomposed within 30 minutes any oxidants,The relative standard deviation for the determina- tion is less than 4%.The chain of the saturated chloro-hydrocarbons is so long (≥3) that the time must be increased.The released chloride my be determined by either ion-selectlve electrode or spec- trophotometry.更多还原
