研究了竹炭吸附对氨基苯酚(PPA)的吸附行为。研究结果表明,竹炭是对氨基苯酚的良好吸附材料,其吸附率可达98.6%。测定了竹炭吸附对氨基苯酚的热效应:其热效应为-18.2kJ/mol;研究了溶液酸度、吸附剂粒径与质量、温度和对氨基苯酚的浓度离对竹炭吸附对氨基苯酚的影响。
Adsorption behavior of the bamboo- charcoal for P-aminophenol was studied. Experimental results showed that bamboo-charcoal had a good adsorption ability for P-aminophenol, adsorption rate of equilibrium were 98.6 %. The adsorption heat of P-aminophenol with Bamboo-charcoal was determined, that were -18.2 kJ/moh The influence factors for pH, the mass and size of adsorbent, temperature and concentration of P-aminophenol were researched.
