探讨了N-甘氨酰甘氨酸-MCI-GEL体系固相萃取分离钯的行为。结果表明,MCI-GEL树脂能够吸附钯与N-甘氨酰甘氨酸(Gl C)形成的配合物。探究出了实验的最佳萃取条件:n(Gl C)∶n(Pd(Ⅱ))=1∶1,c(HCl)=0.05 mol/L,V过柱=1 m L/min,钯的萃取率可达99%。实验测定了小柱的萃取容量为4.8 mg/g,以丙酮为洗脱溶剂,2 m L丙酮以1 m L/min的洗脱速度能完全洗脱钯的配合物。对合成试样中的钯进行了分离和测定,效果良好。 The separation of palladium by N-glycylglycine-MCI-GEL system was investigated. The results show that MCI-GEL resin can adsorb palladium and glycylglycine (Gl C) formed complexes. The optimum extraction conditions were explored: n (Gl C): n (Pd (Ⅱ)) = 1: 1, c Extraction rate of up to 99%. It was experimentally determined that the extraction capacity of the cartridge was 4.8 mg / g and the palladium complex eluted completely with 2 mL of acetone at a rate of 1 mL / min with acetone as the elution solvent. The synthesis of palladium in the sample was separated and measured, the effect is good.
