摘要
试验阴离子表面活性剂十二烷基硫酸钠对Ni2 + —PAN络合物的乳化作用 ,在水相中直接进行尿素中微量镍的比色测定 ,结果与原方法吻合 ,加标回收率 97 0 %～ 10 5 4% ,RSD≤ 0 7%
This article describes the emalsification of Ni 2+ —PAN complex by dodecyl sodium sulphate acting as a kind of anionic surface active agent.The colorimetric determination of trace nickel in urea is carried out directly in water phase.The result coincides with that determined by the traditional method.The labelled recovery is between 97.0%～105.4% and RSD≤0.7%
