Job's Method

The complexation abilities of 5,11,17,23,29,35-hexacarboxy-37,38,39,40,41,42- hexa-methoxy-hydroxamic calix[6]arene extraction of metal ions (Cu2+, Ni2+, Na+, Fe3+, Cd3+, Mn2+, Pb2+) were studied. And the complexation ration of Cu2+ and Pb2+ were obtained by Job's method. The selective removal of Cu2+ (Pb2+) coexisting with alkali metals ions (Na+, K+) and alkaline earth metal ions (Ca2+, Mg2+), heavy metal ions (Zn2+, Mn2+, Pb2+(Cu2+), Ni2+) and anions (CO32-, C2O42-, SO42-, NO3-) were studied separately . The results revealed that the percent of Cu2+(Pb2+) removal in the presence of alkali metals ions and alkaline earth metal ions was over 83.8% (90%) and in the presence of anions was over 90.1% (81.3%) while the percent of Cu2+(Pb2+) removal in the presence of heavy metal ions was lower than 70.6% (70.0%), and the minimum percent of Cu2+(Pb2+) removal in the presence of heavy metal ions was 32.7% (61.2%).
