Abstract

Al(III) and Cr(III) were determined selectively by colorimetry of Bismark Brown R {4,4'[(4-methyl-1,3-phenylene)bis(azo)]-bis(6-methyl-1,3-benzenediamine) dihydrochloride} in the presence of the various cations and anions without the using of any masking agents, but tartrate and citrate ions were interfered. The ligand of Bismark Brown R and complexes of Al(III) and Cr(III) were shown the maximum absorbance at the same wavelength together and both metallic ion were interfered to determine each other, but Al(III) were able to determine after oxidation of Cr(III) to Cr(VI).

Al(III)과 Cr(III)을 여러 양이온과 음이온의 공존하에서 가리움제를 사용하지 않고 Bismark Brown R{4,4'[(4-methyl-1,3-phenylene)bis(azo)]-bis(6-methyl-1,3-benzenediamine)dihydrochloride)을 사용하여 정량하였다. 그러나 타르타르산과 시트르산이 공존하면 방해하였다. Al(III)과 Cr(III)은 같은 파장에서 최대흡광도를 나타내므로 Cr(III)을 Cr(VI)으로 산화시키면 Al(III)과 Cr(III)을 선택적으로 정량할 수 있었다.
