	以玉米秸秆为原料，用1 mol/L盐酸对其进行改性处理，制备改性玉米秸秆吸附剂，用于吸附去除废水中的Cr<sup>6+</sup>。通过静态试验考察了废水pH、吸附剂用量、吸附时间以及Cr<sup>6+</sup>浓度对吸附的影响。结果表明，在废水pH = 3、吸附剂用量5 g/L、吸附时间80 min、Cr<sup>6+</sup>浓度50 mg/L时，改性玉米秸秆对废水中Cr<sup>6+</sup>吸附效果最佳，吸附去除率达到86.94%。<br />
The modified corn straw adsorbent was prepared by treating corn straw with 1 mol/L hydrochloric acid, which was used to remove Cr6+ from wastewater. The effects of wastewater pH, the amount of adsorbent, adsorption time and concentration of Cr<sup>6+</sup> on adsorption were investigated by static test. The results showed that when the pH of wastewater was 3, the dosage of adsorbent was 5 g/L, the adsorption time was 80 min and the concentration of Cr<sup>6+</sup> was 50 mg/L, the modified corn straw had the best adsorption effect on Cr<sup>6+</sup> in wastewater; the removal rate of Cr<sup>6+</sup> was 86.94%.
