Abstract

The raising worldwide water tainting from different sources has delivered admittance to unpolluted drinking water progressively testing. The release of effluents containing colors into water bodies become as a basic ecological worry lately. Regular treatment strategies are insufficient in wiping out these steady and risky poisons, requiring the investigation of novel methodologies. In this review, Cu-doped FeO nanoparticles were easily blended by using a co-precipitation strategy, and their synthetic qualities were entirely analyzed. These nanoparticles showed extraordinary adsorption abilities in the corruption of various color compounds. In particular, manufactured acidic color was focused on for expulsion utilizing metal-doped nanoparticles. Ideal boundaries for maximal acidic color not set in stone by surveying the adsorbent portion, beginning color focus, contact time, and temperature. The pH was distinguished as a critical variable, with the best incentive for maximal adsorption of Congo Red Dye viewed as less than 7. As indicated by late discoveries, Cu/FeO nanoparticles displayed unrivalled adsorption limit with regards to Congo Red Dye color at an ideal pH of 2, a measurement of 0.5 g/500 mL, a contact season of an hour and a half, and a color centralization of 150 ppm at 35° centigrade. Pseudo second order adsorption kinetic model exhibited amazing fitting outcomes for adsorption energy and balance information.
铜改性氧化铁纳米颗粒:在废水处理中有效降解刚果红染料的新型催化剂
全球范围内不同来源的水污染日益严重,使人们越来越难以获得未受污染的饮用水。近来,向水体排放含色素的污水已成为一个基本的生态问题。常规的处理策略不足以消除这些稳定而危险的毒物,因此需要研究新的方法。在这篇综述中,采用共沉淀策略轻松混合了掺铜的氧化铁纳米粒子,并对其合成质量进行了全面分析。这些纳米粒子在腐蚀各种颜色化合物时表现出非凡的吸附能力。特别是,利用掺杂金属的纳米粒子,对制造的酸性颜色进行了重点驱逐。通过调查吸附剂的份量、开始的颜色浓度、接触时间和温度,没有确定最大酸性颜色的理想界限。pH 值被认为是一个关键变量,刚果红染料最大吸附量的最佳激励值低于 7。根据后期发现,在理想的 pH 值为 2、测量值为 0.5 克/500 毫升、接触时间为一个半小时、颜色集中度为 150 ppm、温度为 35 摄氏度的条件下,Cu/FeO 纳米粒子对刚果红染料颜色的吸附极限无与伦比。伪二阶吸附动力学模型显示出吸附能量和平衡信息的惊人拟合结果。
