A two-layer membrane including a polymer layer and a support layer, the polymer layer being disposed on a surface of the support layer. The polymer layer, having a pore size of at most 50 nm and a thickness of 5 nm to 10 μm, is formed of an amphiphilic copolymer that contains both charged groups and hydrophobic groups. The support layer has a pore size of 3 nm to 10 μm, which is larger than the pore size of the polymer layer.

Leachate remediation is performed by synergistic chemical oxidation and photocatalytic-oxidation enhancer system (SCOPES) of municipal landfill leachate to a level that is safe for disposal within regulatory guidelines. The physico-chemical (chemical, spectroscopic, elemental, microstructural and thermal) characteristics of the pre- and post-treated landfill leachate have been investigated to examine the utility of advanced oxidation (AO) processes such as SCOPES to decontaminate the municipal landfill leachate and/or toxic organic wastewater. The experimental results demonstrated successful lowering of chemical oxygen demand (COD) and UV-Vis absorbance for constituent contaminants in the leachate and/or wastewater solutions.

A method of synthesizing a doped carbonaceous material includes mixing a carbon precursor material with at least one dopant to form a homogeneous/heterogeneous mixture; and subjecting the mixture to pyrolysis in an inert atmosphere to obtain the doped carbonaceous material. A method of purifying water includes providing an amount of the doped carbonaceous material in the water as a photocatalyst; and illuminating the water containing the doped carbonaceous material with visible light such that under visible light illumination, the doped carbonaceous material generates excitons (electron-hole pairs) and has high electron affinity, which react with oxygen and water adsorbed on its surface forming reactive oxygen species (ROS), such as hydroxyl radicals and superoxide radicals, singlet oxygen, hydrogen peroxide, that, in turn, decompose pollutants and micropollutants.

An electrolysis electrode and a preparation method therefor, an electrolysis apparatus, and a clothing treatment device. The electrolysis electrode includes a substrate, a transition layer, and an electrode catalytic material layer, and the transition layer is attached to the surface of the substrate, the electrode catalytic material layer is attached to the surface of the transition layer, and the thickness of the transition layer satisfies that: electrons can pass through the transition layer. The transition layer of the electrolysis electrode is relatively thin, so that electrons can pass through the transition layer due to a quantum tunneling effect, and thus the electrocatalytic performance of the electrolysis electrode is basically not affected. Furthermore, the transition layer plays the role of transition connection, and can greatly improve the phenomenon of cracks in the electrode catalytic material layer.

The present invention relates to a method for preparing a simply prepared, safe, nontoxic, and biodegradable modified starch; the present invention further relates to use thereof as an adsorbent in adsorbing heavy metal ions and organic compounds, and belongs to the technical field of modified starch material. Starch is used as raw material and modified with thiourea and tungsten chloride; the starch binds to heavy metal ions through a series of coordination or chelation, and thus produces a heavy metal ion adsorption effect; a starch-based carbon composite is prepared, i.e., a modified starch composite. The simply prepared, environmentally friendly, and recyclable modified starch adsorbent with excellent performance and higher practical value effectively removes He ions and such organic compounds as methylene blue from the wastewater; the modified starch adsorbent is expected to develop into a novel water treatment agent due to low loss rate, biodegradability, and recyclability.
