Abstract:
The chrome content of 8 Korean cements and 11 Korean bleaching detrgents was analyzed by the qualitative DPC method and the quantitative atomic absorption spectrophotometry and UV-visible spectrophotometry. In cements, there was no detectable chrome in 1 sample and the range of chrome content in other 7 samples was 1.32 5.29ppm. The qualitative result was welJ. correlated with the quantitative result. In bleaching detergents, there was no detectable chrome in 4 samples and the range of chrome content in other 7 samples was 0.0329 0.362ppm. However, the qualitative result was not correlated with the quantitative result.
