  • 摘要: 采用超细粉体加工设备制备了天然超细针状羽绒粒子,考察其对模拟染料废水溶液中酸性大红3R、直接耐酸大红4BS、还原大红R的吸附性能,探讨了pH、吸附剂用量等因素对染料吸附的影响。实验结果表明,超细羽绒粒子是一种针状介孔吸附材料,具有连续的孔径分布和发达的孔结构。染料溶液pH为3.0,超细羽绒粒子用量5 g/L时吸附效果最好。对吸附数据进行Langmuir、Freundlich、Tempkin以及D-R吸附模型线性拟合,得出超细羽绒粒子对3种染料的吸附规律最符合Langmuir等温吸附方程,其理论最大吸附容量分别为137.55、108.11和87.72 mg/g。对吸附能计算发现,超细羽绒粒子对酸性大红3R、直接耐酸大红4BS以及还原大红R的吸附是化学吸附过程。研究表明,超细羽绒粒子是一种最具有应用潜力的吸附印染废水中有毒有机染料的高效吸附剂。
    Abstract: Natural superfine needle down particle(NSNDP) was successfully prepared by a self-made machine and applied to remove hazardous dyes acid brilliant scarlet 3R(ABS-3R),direct fast scarlet 4BS(DFS-4BS) and vat scarlet R(VS-R) from aqueous solution.The effects of pH values and dose of adsorbent on the dye adsorption of NSNDP were discussed.The pore size and surface morphology of NSNDP also were investigated by using Micromeritics ASAP 2020 analyzer and scanning electron microscope(SEM).The results showed that NSNDP is a mesoporous material with continuous pore size distribution and abundant pore structure.The optimum conditions for removal of dyes were found to be pH 3.0,adsorbents amount of 5 g/L.Experimental adsorption data were fitted by Langmuir,Freundlich,Tempkin and Dubinin-Radushkevich(D-R) isotherms,and the Langmuir isotherm showing the best fit.The maximum absorptions capacities for the dye were 137.55,108.11 and 87.72 mg/g,corresponding to acid brilliant scarlet 3R,direct fast scarlet 4BS and vat scarlet R respectively.According to the mean free energy values of adsorption(E) calculated using the D-R isotherm model,adsorption of dyes onto NSNDP was chemisorption process.To conclude,NSNDP is a promising absorbent to remove the hazardous dyes from textile effluent.
