摘要

在本手稿中，使用各种技术合成并表征了未涂覆和柠檬酸涂覆的磁性纳米颗粒。本文主要研究了柠檬酸修饰的磁性纳米粒子对溶液中染料的吸附研究。考察了吸附剂用量、吸附时间和染料溶液浓度等因素的影响。此外，动力学和等温线研究证实，吸附过程遵循准二级动力学和Langmuir等温线模型。解吸研究也受到了仔细审查。与未涂覆的磁铁矿纳米颗粒相比，涂覆的磁铁矿纳米粒子显示出更好的吸附能力。

Dye Elimination by Surface-Functionalized Magnetite Nanoparticles: Kinetic and Isotherm Studies

In the present manuscript, uncoated and citric acid-coated magnetic nanoparticles were synthesized and characterized using various techniques. The manuscript mainly focuses on the adsorption study of the citric acid-modified magnetic nanoparticles for dye adsorption from the solution. The effect of several factors, including adsorbent amount, adsorption time, and dye solution concentration, were examined. Additionally, kinetic and isotherm studies confirmed that the adsorption process followed pseudo-second-order kinetics and the Langmuir isotherm model. The desorption study was also scrutinized. The coated magnetite nanoparticles show better adsorption capacity than uncoated magnetite nanoparticles.

期刊介绍： Biointerface Research in Applied Chemistry is an international and interdisciplinary research journal that focuses on all aspects of nanoscience, bioscience and applied chemistry. Submissions are solicited in all topical areas, ranging from basic aspects of the science materials to practical applications of such materials. With 6 issues per year, the first one published on the 15th of February of 2011, Biointerface Research in Applied Chemistry is an open-access journal, making all research results freely available online. The aim is to publish original papers, short communications as well as review papers highlighting interdisciplinary research, the potential applications of the molecules and materials in the bio-field. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible.
