Aluminium has been determined by β-correction spectrophotometry with phenylfluorone (PF)and a non-ionic surfactant,emulsifying OP in pH 8 ammoniacal buffer solution.β-correction spectrophotometric method can eliminate completely the effect of excess PF to increase the analytical sensitivity and decrease error.The results have shown that Beer's law was obeyed over the concentration range 0-15 μg Al(Ⅲ)/25 ml and the relative standard deviation was less than 3.3%.
