  • 摘要: 以柿粉为原料通过甲醛交联固化制备出柿粉树脂(PPR);利用傅里叶红外光谱(FT-IR)、Zeta电位、热变性温度、比表面积等对其进行表征,并探讨其吸附Cu2+和Pb2+的效应。结果表明,(1)PPR对Cu2+和Pb2+的吸附效果显著高于柿粉与活性炭;(2)pH值对吸附平衡影响较大,最佳pH值范围为5.0~6.0;(3)PPR对Cu2+和Pb2+的吸附在180 min内可达到吸附平衡,提高吸附温度可提高吸附速率,其吸附动力学数据可用拟二级速率方程良好拟合;(4)提高金属离子初始浓度可增加平衡吸附量,Freundlich和Langmuir方程可分别拟合PPR对Cu2+(R2 > 0.98)和Pb2+(R2 > 0.99)的吸附等温线;(5)PPR(2.0 g/L)可吸附混合重金属溶液中83.73% 的Cu2+和98.63% 的Pb2+;(6)PPR可循环使用5次以上;(7)PPR对Cu2+与Pb2+的吸附效应可能是静电吸附与配位反应共同作用的结果。该研究结果表明,PPR是一种有应用前景的处理含重金属废水的备选材料。
    Abstract: A new adsorption resin (persimmon powder resin, PPR) was developed by immobilizing persimmon powder with formaldehyde, and it was characterized by FT-IR spectra, Zeta potentials, thermal denaturation temperature and BET specific surface area. The adsorption properties to Cu2+ and Pb2+ were investigated. The adsorption capacity of Cu2+ and Pb2+ on PPR was much higher than persimmon power and activated carbon. The results indicated that the adsorption capacity of Cu2+ and Pb2+ depended on the solution pH, and the optimal pH range was 5.0~6.0. The adsorption of Cu2+ and Pb2+ was rapid which could reach adsorption equilibrium within 180 min, and the adsorption kinetics data were well fitted with the pseudo-second-order rate model. Higher temperature led to higher adsorption rate and higher concentration of solutions led to higher equilibrium adsorption capacity. The adsorption isotherms of Cu2+ on PPR could be well described by Freundlich equation (R2 > 0.98) while the adsorption isotherms of Pb2+ on PPR were well fitted with the Langmuir equation (R2 > 0.99). The resin exhibited high adsorption capacity towards Cu2+ and Pb2+ from coexisting metal ions solution, and the pollutant removal reached 83.73% and 98.63% when the adsorbent dose was 2.0 g/L, respectively. The regeneration and reusability tests result indicated the PPR was suitable for repeated use for more than five cycles. The adsorption mechanism of Cu2+ and Pb2+ on PPR might be the combination of electrostatic attraction and coordination reaction. This suggested that the resin can be used as an active biosorbent for the removal of heavy metal ions from aqueous environment.
