title: [Study on determining the composition of ternary complex (AI-CAS-CTMAB) with the ratio of double peak values at double wavelengths by UV spectrophotometry].
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 epsilon 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: [formula: see text] 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.
