Abstract: |
Using mixed solvent CS2-NMP to extract Xinjiang Heishan coal for 90h , and study the adsorption of methyl malachite green and p-phenylenediamine with the residues . The research intended to focus on the adsorption time, temperature, dosage of residues , pH and concentration of the dye on the adsorption effect , and how to get the best conditions . The results show that the best conditions of malachite green are room temperature , with the pH 2 to 10 , the initial concentration of the dye 100mg/L , the adsorption time 120min , and the dosage of the residues 0.5g/100mL; And the best conditions of p-phenylenediamine are at room temperature , with the pH below 6 , the initial concentration of the dye 100mg/L , the adsorption time 90min , and the dosage of the residues 1.0g/100mL. Only in these conditions can the malachite green and p-phenylenediamine be effectively decolorized , with the decolorization reaching above 90%.
