【摘要】 利用UV辐射作用可将水溶液中有机氟化物完全光解,用WL-15型离子计或氟离子选择电极直接测定氟含量.对光解时间、最适酸度、氧化剂的选择以及干扰物质等都做了研究.测定结果的相对标准偏差为2.54‰.更多还原

【Abstract】 UV-irradiation technique made the decomposition of organofluorine compounds in water. The released fluoride ion was determined by means of fluoride ion-selective electrode using a citrate buffer mixture as TISAB. The method described is suitalbe for determining ppm-ppb levels of organic fluorine in aqueous solution and the total amount of fluorine when mixed with other fluorides.更多还原
