Abstract

The invention discloses a graphene oxide-gadolinium hydroxide composite material, a preparation method and an application thereof. The present invention prepares graphene oxide-gadolinium hydroxide composite material (Gd(OH)) by direct precipitation method and hydrothermal synthesis method 3 / GO) to adsorb and remove malachite green (MG) and phosphate ion (PO) in the solution 4 3‑ ), and Gd(OH) by SEM, FT-IR, etc. 3 The structure of the / GO composite was characterized by analyzing malachite green (MG) and phosphate ion (PO) under different conditions of pH, time, temperature and initial mass concentration. 4 3‑ ) adsorption effect was discussed, the optimal adsorption conditions were determined, and the maximum adsorption capacity of malachite green and phosphate ion was obtained by fitting the Langmuir isotherm adsorption equation to be 495mg / g and 364.8mg / g respectively, the adsorption effect is remarkable .

Description

【Technical field】 [0001] The invention belongs to the technical field of preparation of water treatment agents, and in particular relates to a graphene oxide-gadolinium hydroxide composite material, a preparation method and an application thereof. 【Background technique】 [0002] There are many wastewater treatment technologies, such as: flocculation, membrane filtration, solvent extraction, biosorption, chemical precipitation, ion exchange, reverse osmosis, electrocoagulation, sintering, electrolytic precipitation, coagulation and adsorption, etc. Among them, the adsorption method has become a widely used method for removing pollutants due to its advantages of cheap production and simple operation and treatment process. It is very important to design new adsorbents with excellent adsorption capacity. [0003] There are many kinds of adsorbents, which can be mainly divided into three categories: [0004] The first category is more common porous adsorption materials, such as ...
