摘要
用四阶导数分光光度法,无需经显色与萃取便可直接测定环境水中十二烷基苯磺酸钠的含量。本法抗干扰能力较强,检出限为0.7mg/l(即2×10^(-6)M),回收率为96～103%。
Sodium dodecylbenzene sulfonate in environmental water can be determined directly by4th-order derivative spectropnotometric method. This method tolerates considerable concentrationof dodecylbenzene and phenol. The detection limit is 0.7mg/l (i. e. 2 μM). The recovery isfound to be 96-103(%).
