摘　　要：考察了RD复合净水剂吸附处理阳离子艳兰染料RL废液的实验条件,探讨了RD吸附脱色的实质。结果表明,加入0.3gRD到浓度为200mg/L的染液中,在25℃、pH=7.0条件下,吸附时间为10m in时,废液的脱色率达到80%,RD单位质量吸附量为10.7mg/g;当50mg/L的染料废液中,RD的投加量为0.2g时,脱色率达到了96%以上,RD单位质量吸附量为8.12mg/g;pH值和温度对吸附脱色效果影响不显著,而且RL废液的浓度增大,RD单位质量吸附量增大,但是脱色率有所下降。RD对染料的吸附符合Langmu ir吸附模型。The adsorption decolouration capacity on the cationic brilliant blue RL by the RD complex water purifying agent was studied.The results showed that by adding 0.3 g RD into a dye solution with concentration of 200 mg/L at conditions of 25 ℃,pH=7.0 for 10 min as absorption time,the decolouration rate reached 80% and the adsorption of per mass of RD was 10.7mg/g.When RD was added with dosage of 0.2 g into a dye solution with concentration of 50 mg/L,the decolouration rate reached more than 96% and the adsorpti...
