Florisil solid-phase extraction cartridges were evaluated for cleanup of organochlorine pesticide residues in food extracts. Elution patterns and recoveries were determined for 24 organochlorine pesticides. A range of elution solvents was evaluated. A 2% ethyl ether-petroleum ether eluant optimized overall recoveries while minimizing interferences from coextractants.
对弗罗里硅土固相萃取柱进行了评估，以净化食品提取物中的有机氯农药残留。测定了24种有机氯农药的洗脱模式和回收率。评估了一系列洗脱溶剂。2%乙醚-石油醚洗脱剂优化了总体回收率，同时将共萃取剂的干扰降至最低。
