GC-MS测定城市污泥中壬基酚及壬基酚聚氧乙烯醚的方法研究

摘要

A simple and sensitive method for determination of nonylphenol(NP), nonylphenol-mono-ethoxylate (NP1EO) and nonylphenol-di-ethoxylate(NP2EO) in municipal sludge was developed using gas chromatography/mass spectrometry (GC-MS). The results show that detection limit of the method is 0.004 mg/kg, the recovery is in the range of 80.2%~ 96.7%. This method is accurate and highly reproducible, and can be used to determine NP, NP1EO and NP2EO in municipal sludge.%研究建立气相色谱串联质谱法测定污泥中壬基酚、壬基酚单氧乙烯醚及壬基酚双氧乙烯醚的方法。该方法的检出限为0.004 mg/kg，方法的精密度RSD为1.09%~2.72%，回收率为80.2%~96.7%。该方法操作简单，结果准确、可靠，重现性好，检出限低，实用价值高，适用于污泥中壬基酚、壬基酚单氧乙烯醚及壬基酚双氧乙烯醚的测定。
