摘　　要：染料废水处理成本高一直是困扰吸附材料应用的问题之一,为此,选取几种植物纤维固体废弃物,开展植物纤维微球的制备及其对不同染料溶液的吸附特征研究。研究结果表明,3种植物纤维微球对碱性品红、结晶紫溶液的吸附容量都较大,而对中性红溶液的吸附容量相对较小;杏仁壳粉微球对染料溶液的吸附效果最好,其对结晶紫、中性红、碱性品红的去除率分别达到87.21%,70.37%,85.69%;不同含量植物纤维微球对3种染料溶液均具有较好的吸附效果,当植物纤维的质量分数为1%时,吸附效果最佳。活性炭微球对染料溶液的吸附速率最快,达到吸附平衡所需时间约为60 min。吸附动力学研究表明,3种植物纤维微球对3种染料溶液的吸附均符合Freundlich等温吸附方程,其吸附机理仍以物理吸附为主。植物纤维微球适用于染料废水的治理,可实现以废治废的目的。The high cost has been one of the problems that puzzls the application of adsorption materials. Therefore, several plant fibers usually treated as solid waste were selected and made into plant fiber micro- spheres, and adsorption characteristics of the plant fiber microspheres treating different dye solution were studied. The results showed that adsorption capacity of three kinds of plant fiber microspheres on basic fuch- sin and crystal violet solution were larger,while their adsorption capacity on neutral red solution were poor. The adsorption capacity of almond shell powder microsphere on dye solution was the best,which the removal rate of crystal violet, neutral red, basic fuchsin were 87.21% ,70. 37% ,85. 69% , respectively. The different content of plant fiber microspheres all had good adsorption capacity on three kinds of dye solution. When the mass fraction of plant fiber was 1% ,the adsorption capacity of microspheres was the strongest. The adsorption rate of activated carbon microsphere to dye solution was the fastest, and the time to reach adsorption equilibri-um was about 60 min. The adsorption kinetics studies showed that the adsorption of three kinds of fiber micro- spheres to three dye solutions followed the Freundlich isotherm adsorption equation, and the adsorption mech-anism was still dominated by physical adsorption. It can be seen that the plant fiber microsphere is suitable for the treatment of dye wastewater, so as to achieve treating waste by waste.
