摘　　要：采用松果粉末作为吸附剂,进行了模拟含铬废水中C(rVI)吸附试验研究,考察了不同吸附条件(吸附剂投加量、初始溶液pH值、C(rVI)初始浓度、温度)对C(rVI)去除效果的影响,并用红外光谱分析了吸附机理.结果表明:温度越高、pH值越低、投加量越大、C(rVI)初始浓度越低越有利于C(rVI)的去除.红外光谱分析表明,与Cr相互作用的基团主要是氨基、羟基、羧基和硫酸基.The adsorption and desorption experiments were researched by using the pine cone powder （PCP） as the adsorbent to remove the chromium （Ⅵ） from aqueous solution. The affecting factors on the Cr （Ⅵ）removal rate such as dosage of adsorbent, pH, initial concentration of Cr （Ⅵ） and temperature were evaluated, and mechanisms for chromium （Ⅵ） removal are discussed by FTIR analysis. The results show that Cr （Ⅵ）remova rate increased with the decrease of the size of adsorbent, pH and initial Cr （Ⅵ） concentration, and with the increase of adsorbent dosage and temperature. According to the desorption experiment under different pH, FTIR analysis indicated that amino, hydroxy, carboxyl and vitriol groups are the main functional grops in the reaction with Cr.
