Abstract
Rare earth elements (REEs) have versatile applications in various industries and are thrown as industrial waste waters, which leads to serious environmental issues.This paper describes the adsorption efficiency of nano copper ferrite on REEs namely lanthanum and cerium in their trivalent states at room temperature and at the optimum conditions of pH, contact time, adsorbent, adsorbate dosage,temperature etc. The batch adsorption studies were conducted for the adsorption studies using ICPAES (Inductive coupled plasma atomic emission spectro photometer). In addition the data is studied for Langmuir and Freundlich models and observed that data well fitted to Langmuir monolayer adsorption. From the graph and intercept values of theoretical and experimental values, the pseudo second order kinetics are followed. Thermodynamic parameters reveal that reaction is spontaneous and endothermic. From the over all observations like fast kinetics, chemical stability, high adsorption capacity it is concluded that nano CuFe 2 O 4 has maximum efficiency for the adsorption of REEs
期刊介绍：
Oriental Journal of Chemistry was started in 1985 with the aim to promote chemistry research. The journal consists of articles which are rigorously peer-reviewed. The journal was indexed in Emerging Science citation index in 2016. The Editorial board member consists of eminent international scientist in all fields of Chemistry. Details of each member and their contact information is mentioned in website. The journal has thorough ethics policies and uses plagiarism detection software(ithenticate) to screen each submission. The journal has recently partnered with publons as a part of making our reviews more transparent. The journal has recently incorporated PlumX for article level matrix. The journal is promoting research on all social and academic platforms mentioned in PlumX guidelines. The journal uses google maps to improve on the geographical distribution of Editorial board members as well as authors.
