Interactions between organic flocculant PAN–DCD and dyes

In order to investigate the chemical interaction between PAN–DCD and dyes, the IR spectra of PAN–DCD, dye K-6G, and the floc formed were comparatively analyzed . The IR spectrum of PAN–DCD exhibited the bands at 1546, 827 and 2190 cm −1 , which can be attributed to the triazine and amidine, respectively.

Interactions between organic flocculant PAN–DCD and dyes

The flocculant effectively decolorized the examined dyes in their aqueous solutions under acid condition. By comparing the IR spectra of dyes with that of PAN–DCD and that of flocs formed, weak chemical interactions between amino in PAN–DCD side chain and sulfonic acid group in the dye molecules were observed through the formation of –NH

Effect of Dye Structure on the Interaction between Organic

On the basis of the experimental methods of flocculated decolorization and equilibrium dialysis, the effect of dye structure on the interaction between organic flocculant PAN-DCD and dye has been explored. It was found that, under acidic conditions, PAN-DCD is effective in the decolorization of dyes with sulfonic acid groups and carboxyl groups and that the number of these groups has something

Removal of acid and direct dye by epichlorohydrin

A cationic organic flocculant epichlorohydrin–dimethylamine (EPI–DMA) was employed for the treatment of acid and direct dye. The study aims at investigating the flocculation performance of EPI–DMA for the model dye, and corresponding floc aggregation properties, which were determined by jar test and photometric dispersion analysis, respectively.

However, the interaction between dye-LBF particles and dye-PAC particles was weakened due to the lack of positive charges (Rong et al. 2013b). As a result, the color removals and floc properties in LBF + PAC
