摘要
采用流动注射在线蒸馏法同时测定了水样中挥发酚及氰化物。结果表明:其线性范围在0—100Lg/L时,均具有良好的线性关系,挥发酚和氰化物的方法检出限分别为1.2Lg/L和1.0Lg/L,精密度RSD均小于3%,挥发酚和氰化物平均回收率分别为90.6%和93.4%。
The method of simultaneous determination of volatile phenol and cyanide in water by flow injection-on line distillation analysis is illustrated. The calibration graphs obtained by the method are linear up to 100μg/L of volatile phenolics and cyanide, the detection limit of volatile phenol and cyanide are 1. 2μg/L and 1. 0 μg/L respectively. RSD is less than 3%, The recoveries of volatile phenol and cyanide are 90. 6% and 93.4% respectively.
