摘　　要：结合实际工作经验,对GB／T16488-1996所规定的分析条件进行了进一步的探讨,研究了氯化钠、硫酸钠的用量对测定结果的影响,同时用工作曲线代替标准曲线,可使实测样品回收率提高10.0％以上,进一步提高测定结果的准确度。The testing conditions specified in standard GB/T 16488-1996 are explored and the impact of sodium chloride and sodium sulfate dosages on the measurement result is studied based upon application experience. When the work profile is used to replace the standard profile, the sample recovery rate can be increased by over 10% , which further improves the measurement accuracy.
