研究了用AmberliteXAD-2000树脂微柱富集吡咯烷二硫代氨基甲酸铵（APDC）络合物中痕量金属（Co、Ni、Cu和Cd）的新方法。用1 M HNO 3的丙酮溶液洗脱富集在树脂上的金属络合物后，用火焰原子吸收光谱法（FAAS）测定金属含量。分析参数，如样品pH值，络合剂的量，洗脱剂类型，树脂量，样品体积，样品流速，和基质离子的影响进行了研究，从水溶液中的金属的回收率。相对标准偏差（R.S.D.）方法的回收率<6%。使用两种经认证的参比物质（CRM TMDW-500饮用水和CRM SA-C桑迪土壤C）确认了该方法的验证。该方法已成功地应用于土耳其东黑海地区（特拉布宗市）的一些溪流沃茨和蘑菇样品。
A new method for the preconcentration of some trace metals (Co, Ni, Cu, and Cd) as complexed with ammonium pyrrolidynedithiocarbamate (APDC) was developed using a mini-column filled with Amberlite XAD-2000 resin. Metal contents were determined by flame atomic absorption spectrometry (FAAS) after the metal complexes accumulated on the resin were eluted with 1M HNO3in acetone. The effects of the analytical parameters such as sample pH, quantity of complexing agent, eluent type, resin quantity, sample volume, sample flow rate, and matrix ions were investigated on the recovery of the metals from aqueous solutions. The relative standard deviation (R.S.D.) of the method was <6%. The validation of the method was confirmed using two certified reference materials (CRM TMDW-500 Drinking Water and CRM SA-C Sandy Soil C). The method was successfully applied to some stream waters and mushroom samples from Eastern Black Sea Region (Trabzon city) of Turkey.
