Study on the technology of reducting and complexing bleach of kaolin;

As the test sample,a certain place’s kaolin of Fujian was bleached with reduction and complexing ways according to its physical and chemical properties.

The single-site ligand model was applied to determine the complexing ability between cupric ion and DOM(Dissolved Organic Matter)that was extracted from the litters of Cinnamomum chekiangense at different decomposition stages.
