OBJECTIVE To develop a simple and sensitive method for determination of Aluminium in Sucral-fate tablets.METHODS A novel and sensitive spectrophometric method for rhe determination of Aluminium was developed ,which is base on the coupled reaction of chrome azurol S-ammonium bromohexadecyl pyridine-tween-20 content in acetic acid medium .the Aluminium content was determined photometric ally at 620 nm.RESULTS Alu-minium in the linear concentration range of 0~0.20 mg? L-1 was determined with a detection limit of 0.008 mg?L-1 .RSD 0.75%~3.95% and the recovery rate 97.8%.CONCLUSION The method has been applied to the determination of Aluminium in Sucralfate tablets samples .The possible reaction mechanism is also discussed .
