摘要:
讨论吸附时间、温度、pH值、转速和离子浓度等对废弃雪虾壳吸附染料的影响,并探讨其等温吸附模型.结果表明:雪虾壳对染料的吸附随着转速的增大而增加,最佳吸附温度为40 ℃,吸附平衡时间为60 min;雪虾壳对阳离子染料的吸附随着pH值增大及离子浓度的减小而增大,而对阴离子染料的吸附则随着离子浓度的增大而增大,pH值的变化对吸附影响不大等.温吸附模型拟合结果表明:雪虾壳对结晶紫和孔雀石绿的吸附为线性等温吸附,对碱性品红为Freundlich型等温吸附,对酸性黄的吸附为Langmuir型等温吸附.
Abstract:
In this paper, the effects of temperature, pH value, rotation speed and ionic strength on the adsorption of dye by discarded snow shrimp shells were discussed as well as the isothermal adsorption model. The results showed that the adsorption capacity of snow shrimp shells increased with the increase of rotation speed, the optimum adsorption temperature was 40 ℃ and adsorption equilibrium time was 60 min. The adsorption capacity to cationic dye increased with the increase of pH and the decrease of ionic strength; the adsorption capacity to anionic dye increased with the increase of ionic strength, pH change had no obvious influence to it. Contrast to anionic dye, snow shrimp shells had better adsorption capacity to cationic dye. The paper also indicated that adsorption equation of the crystal violet and malachite green belonged to Linear isothermal adsorption, and the equations of basic fuchsin and acid yellow belonged to Freundlich isothermal adsorption and Langmuir isothermal adsorption respectively.
