Abstract:A novel conductive polymer adsorbent poly(m-phenylenediamine) was synthesized by a simple chemical method and applied to the Na+adsorption in pulping black liquor of Xuan paper meteor grass.The adsorption materials were characterized by scanning electron microscopy and Fourier transform infrared spectroscopy. The effects of adsorbent dosage, adsorption time and the concentration of Na+ in pulping black liquor of Xuan paper meteor grass were investigated. The results showed that the poly(m-phenylenediamine)had a particle size of 0.5 μm and had a trapezoidal structure which was favorable of adsorption.The amount of poly(m-phenylenediamine)Pulping black liquor of 10 g/100 mL and the removal rate of Na+ in pulping black liquor of Xuan paper meteor grass was 73.3%. The results of mechanism analysis showed that the lagergren quasi-second-order kinetic equation could well describe the adsorption process of Na+ on poly(m-phenylenediamine), and the adsorption was mainly chemical adsorption. |
