以Arochlor1242为例,阐述了采用超声波萃取、弗罗里硅土和浓硫酸净化、气相色谱(GC/ECD)分析了土壤和沉积物中的多氯联苯混合物。研究表明:方法检出限0.03mg/kg,加标回收率65.7%~103%之间,RSD为6.2%~11.9%。
以Arochlor1242為例,闡述瞭採用超聲波萃取、弗囉裏硅土和濃硫痠淨化、氣相色譜(GC/ECD)分析瞭土壤和沉積物中的多氯聯苯混閤物。研究錶明:方法檢齣限0.03mg/kg,加標迴收率65.7%~103%之間,RSD為6.2%~11.9%。
이Arochlor1242위례,천술료채용초성파췌취、불라리규토화농류산정화、기상색보(GC/ECD)분석료토양화침적물중적다록련분혼합물。연구표명:방법검출한0.03mg/kg,가표회수솔65.7%~103%지간,RSD위6.2%~11.9%。
Taking Arochlor 1242 as an example,this paper introduces the methods of analyzing the Arochlors in soil and sediment by using ultrasonic extraction, Florida silica dust and concentrated sulfuric acid purification,and GC/ECD. The results show that the method detection limit is 0.03mg/kg,the recovery rate is between 65.7% and 103%,and the RSD is between 6.2% and 11.9%.
