| Abstract: | The extraction and HPLC method of metal
coordinate is provi ded.A yellow coordinate,produced from reaction of aluminum with
8-Hydroxyquinoli ne has been extracted with chloroform and determined with HPLC using PC-8
alkyl bonded phase and Uvdetector detecting at the wavelength of 390nm.The mob ile phase
is a mixture of methyl alcohol and ethyl acetate and water(402040,v/ v).The contents of
aluminum in drinking water are determined in a range of 20-70 0ug/L.The conditions of
extraction,extraction efficiency and chromatographic sep aration conditions have been
studied and the sensitivity,selectivity and reprodu cibility of determination have been
discussed. |
