摘　　要：以NaOH对柚子皮进行改性,制备改性柚子皮生物吸附剂,采用静态吸附、分光光度法考察吸附剂投入量等因素对染料水溶液中碱性品红吸附效果的影响。结果表明:当改性柚子皮投加量0.09g,吸附时间35 min,碱性品红初始浓度为25 mg·L^(-1),pH为4,温度为45℃时,吸附率达到88.52%,比改性前提高了57.86%。NaOH solution was used to modify the pomelo peel as the raw material.The effects of the amount of the adsorbent,the adsorption time,the initial concentration of basic magenta,the initial pH and the adsorption temperature on the adsorption of basic magenta in aqueous solutions were discussed using static adsorption method.The experimental results showed that the five conditions were the best when the amount of adsorbent was0.09g,the adsorption time was35min,the initial concentration of dye was25mg·L^-1,the initial pH of the dye was4,and the adsorption temperature was45℃.The adsorption rate of modified pomelo peel was88.52%,which was57.86%higher than that before modification.
