Abstract

A catalytic and adsorptive material prepared by a ferro (Fe)-manganese (Mn)-rich pelagic clay and a method thereof are provided. The catalytic and adsorptive material with clay as a main body is designed directed to the chemical composition and structural characteristics of the pelagic clay. For the pelagic clay with relatively high content of Fe and Mn, Fe and Mn exist in clay in a state of amorphous microconcretion. Moreover, Fe and Mn in the pelagic clay can be used as a micromotor for Fenton catalytic reaction under specific conditions to dissolve organic matters, thereby being capable of being used as a Fenton catalyst for water purification. In this present invention, pelagic clay with huge amount of resource reserves in the world ocean is used as raw materials to be prepared into a catalytic material for environmental remediation, which is of innovative significance.

Description

CATALYTIC AND ADSORPTIVE MATERIALS PREPARED BY FERRO
(Fe)-MANGANESE (Mn)-RICH PELAGIC CLAY AND METHOD THEREOF
TECHNICAL FIELD
[01] The present invention relates to the technology for preparing a catalytic and adsorptive material by a ferro (Fe)-manganese (Mn)-rich pelagic clay and an application thereof. Directed to the composition and structural characteristics of pelagic clay, a Fenton catalyst with clay as a main body and with Fe-Mn microconcretion as a micromotor is designed and prepared as an environmental repairing material for sewage purification treatment.
BACKGROUND ART
[02] Fe-Mn-rich pelagic clay sediments mainly consist of mixed illite (I) montmorillonite (M) layer minerals (VM), which contains a small amount of feldspar, quartz, kaolinite, calcite, and the like, and meanwhile contains amorphous
Fe-Mn microconcretion. These substances coexist in a relatively uniform physical mixture. Special marine environment enables pelagic clay to be featured by unique composition and structural characteristics compared with earth's surface clay, such as tine particles, poor crystallinity, more structural defects, large specific surface area, high content of Fe and Mn. The Fe-Mn-rich pelagic clay sample related in the present invention includes the following chemical composition: 1.52 wt% KO, 7.37 wt%
Na20, 9.87 wt% CaO, 9.67 wt% Al:0s, 30.56 wt% SiO, 21.68 wt% Fe Oz and 6.17 wt% MnO. Fe element mainly exists in a valence state of Fe (III) and contains a small amount of Fe (II) valence state, while Mn element mainly exists in a valence state of
Mn (IV). These Fe-Mn compounds are partly contributed by symbiotic Fe-Mn concretion and are partly derived from structural ions in clay mineral lattices.
[03] In recent years, water pollution caused by organic dyestuff and other compounds has been increasingly serious. In the face of such an environmental problem, adsorption technologies, membrane filtration technologies, biotreatment technologies, photocatalytic degradation technologies and advanced oxidation technologies including Fenton catalysis have been developed successively. Due to the features such as, low cost, availability, excellent treatment effects on pollutants, environmental friendliness and low energy consumption in experimental process, clay and composite clay-based catalytic or adsorptive materials have been widely applied in many fields such as, Fenton catalysis, photocatalysis and adsorption. Fenton catalysis is an advanced oxidation technology. The technology uses Fe (II) or Fe (III) to catalyze hydroxyl radicals (-OH) generated by H20:2 and other reactive oxygen species (ROS), thereby oxidizing organic dyestuff and other pollutants into small molecules such as,
CO; and H:0O. At present, researchers have been mainly focused on iron compounds/composite heterogeneous clay Fenton catalysts or Fenton-like catalysts; for example, in the "Construction of Multiphase Magnetic Bentonite Fenton System and its Application Research", Ma Jianchao, Chang Jiali, Zhang Duoduo, Zhao
Xiaodong, Ma Hongzhu, Xiao Yuqiang, Ma Qingliang, Journal of Taiyuan University of Technology, 2015, 46: 399-404, Fe3O,/bentonite has been prepared as a Fenton catalyst by a coprecipitation method to degrade methyl orange, and the maximum decolorization rate is up to 96.72%. In the "Study on the Catalytic Degradation of
Coking Wastewater by Carbon-Pillared Magnetic Bentonite", Xiao Yuqiang, Zhang
Qingfang, Qiao Chen, Ma Qingliang and Ma Jianchao, Coal Technology, 2017, 36: 280-282, a composite carbon-pillared magnetic bentonite water treatment agent has been prepared by a solvothermal method, and the maximum Fenton degradation rate on phenol is up to 95.59%. In the paper of "Multiphase Fenton-Like Treatment of Aged
Landfill Leachate by Zirconium-Pillared Bentonite Loaded Nano-Fe;04", Ma Cui, Liu
Yaqi, Zhang Hanxu, Yuan Pengfei and He Zhengguang, Journal of Huagiao University (natural science edition), 2018, 39: 844-850, a Fe304/zirconium-pillared bentonite catalyst has been prepared by a coprecipitation method, achieving good treatment effects on aged landfill leachate. In the paper of "Degradation of Tetracycline by
Catalyzing Persulfate by Composite ATP@Fe;O0s Materials", Ma Qianqian, Wu
Tianwei, Zhao Mingyue, Hou Jianhua, Wang Shengsen, Feng Ke and Wang Xiaozhi,
Chinese Journal of Environmental Engineering, 2020, 14: 2463-2473, a
Fe30/attapulgite (ATP) Fenton-like catalyst has been prepared by a coprecipitation method, and the maximum degradation rate on tetracycline is up to 98.75%. Currently, most of the Fenton catalysts for the degradation of organic dyestuff and other pollutants in water are synthetic iron-containing composite materials, but there is no study on Fenton catalyzation by means of natural Fe-Mn-rich clay, especially pelagic clay.
