摘要： 通過對凹凸棒土進行鹽酸預處理、苯基三甲氧基硅烷表面改性和復合雙硫腙,制備了復合固相萃取填料(DZ@ATP).采用掃描電子顯微鏡(SEM),、X射線能譜儀(EDS),、傅里葉變換紅外光譜儀(FI-IR)、X射線光電子能譜儀(XPS)對其進行表征,確定了最佳固相萃取條件.考察了DZ@ATP對水中Cd2+,Co2+,Cu2^(+),Cr3+,Pb2+,Sb3+,Sn2+,Tl+,Zn2+,Tb3+,Ag+,Hg2+的吸附性能.吸附容量分別達到15.99,13.45,14.72,12.97,15.77,13.15,14.93,13.81,14.09,13.11,15.82,14.98 mg/g.通過固相萃取與電感耦合等離子體質譜儀(ICP-MS)聯(lián)用測定了水樣中重金屬離子的含量,檢出限分別為0.041,0.027,0.033,0.047,0.063,0.017,0.052,0.084,0.019,0.018,0.056,0.040μg/L.
