Abstract

This study involves the production of a novel biosorbent obtained from Cortaderia selloana flower spikes (CSFs). Magnetic C. selloana flower spikes (nM∞CSFs) was applied as an ideal biosorbent for the elimination of dyes from water. They were utilized for the removal from aqueous solutions of malachite green (MG) and methylene blue (MB) dyes. The analyses of the equilibrium were done under certain experimental parameters such as contact time, initial dye concentration, pH, and quantity of biosorbent. The rapid intake of dyes to reach the equilibrium in a short period time showed the effectiveness of nM∞CSFs to adsorb MG and MB. The experimental information of MB and MG was obtained from the Langmuir model and it confirmed the magnificent dye biosorption ability; 72.99 mg/g for CSFs/MB, 119.05 mg/g for nM∞CSFs/MB, 31.06 mg/g for CSFs/MG, and 56.50 mg/g for nMCSFs/MG. Langmuir’s model affirmed the excellent dye biosorption ability. The pseudo-second-order kinetic model displayed a great fit to the experimental result for the removal of MG and MB. The nMCSFs compared with raw biosorbent affirmed that the magnetic form of the biosorbent has a greater removal ability for MB and MG. nMCSFs is a noteworthy biosorbent for MB and MG removal from wastewater.

  • HIGHLIGHTS
  • Magnetic Cortaderia selloana flower spikes (nM∞CSFs) was synthesized for the biosorption of dyes

  • FT-IR and SEM analysis were used for characterization.

  • The Langmuir isotherm model fitted the data of the adsorption for nM∞CSFs

  • nM∞CSFs is a noteworthy biosorbent for MB and MG removal from wastewater.

  • A NOVELTY STATEMENT
  • This novel biodegradable biosorbent (magnetic-C. selloana flower spikes-(nM∞CSFs)) has many different functional groups to bind MG and MB from aqueous medium. The method to bring the magnetic form was well described and gives an astronomically immense capacity for the abstraction of the dyes. It resists in acidic or basic medium and has a vigorous structure. It has an immense capacity for the dyes compared to other biosorbents. It can be cited by a sizably voluminous number of investigators or researchers when it is published because it is incipient biosorbent in the literature and can be utilized as a novel biosorbent for the removal of dyes.

摘要

这项研究涉及从Cortaderia selloana花穗(CSFs)获得的新型生物吸附剂的生产。磁性卷柏花刺(nM∞CSFs)被用作从水中消除染料的理想生物吸附剂。它们用于从孔雀石绿(MG)和亚甲基蓝(MB)染料中去除。在某些实验参数下进行平衡分析,例如接触时间,初始染料浓度,pH和生物吸附剂的量。快速吸收染料以在短时间内达到平衡显示nM∞CSFs吸附MG和MB的有效性。MB和MG的实验信息来自Langmuir模型,证实了其强大的染料生物吸附能力。72.99毫克/克为的CSF / MB,119.05毫克/克为nM∞CSFs/ MB,31.06毫克/克为的CSF / MG,和56.50毫克/克为nM的CSF / MG。Langmuir的模型肯定了其优异的染料生物吸附能力。拟二阶动力学模型与去除MG和MB的实验结果非常吻合。网管关键成功因素与肯定了生物吸附剂的磁形式对MB和MG更大的去除能力生生物吸附剂相比。纳米的CSF是从废水MB和MG除去一个值得注意的生物吸附剂。
