Abstract In the present paper，the composition of complex Al-CAS-CTMAB was studied with the ratio of double peak values at dual-wavelengths by UV spectrophotometry. First, the composition of complex of Al-CAS was determined in this method，Al∶CAS=1∶2. The absorption of ternary complex(Al-CAS-CTMAB) was determined with reference reagent of the complex Al-CAS. The ε values of Al-CAS and Al-CAS-CTMAB were determined with water reference. The composition of complex Al(CAS)n1(CTMAB)n2 was calculated with the formula:
N=n1/n2=(ΔA2εMRλ1-ΔA1εMRλ2)/(ΔA2εRλ1-ΔA1εRλ2)
CAS∶CTMAB=1∶1;Al∶CAS∶CTMAB=1∶2∶2. The calculated value and that obtained by traditional method are agreeable. The method is reliable for determining composition of ternary complexes.
