摘　　要：合成了一种杯芳烃衍生物C4O,并以此为萃取剂,研究了其对镍、钴等金属离子的萃取性能。结果表明,萃取剂C4O对镍、钴表现出较强选择性,在水相pH=6、C4O浓度10 mmol/L、乙酸乙酯作稀释剂、相比(O/A)1∶1、室温下振荡接触60 min、振荡速度240 r/min条件下,镍离子萃取率可达93.9%,镍、钴离子分离系数可达388.38。A calixarene derivative C4O was synthesized,and then was used as an extractant to investigate its extraction behavior for metallic ions of Ni,Co,Cu,Zn,Mn and Cr.Results show that C4O has good selectivity to Ni and Co.With the pH of the aqueous phase at 6,C4O concentration of 10 mmol/L,O/A of 1∶1,and using ethyl acetate as the diluent,the extraction rate of nickel ions can reach 93.9%with Ni/Co separation coefficient up to 388.38 after 60 min⁃oscillation at speed of 240 r/min at a room temperature.
