Finely porous metallic membranes have been often made of stainless steel and palladium and are mainly used in gas separations, but they can also be used for water treatments at high temperatures or as a membrane support materials. Ceramic membranes are mostly made from the following materials e.g. TiO2, ZrO2, Al2O3 and SiO2.
Humic Acid is a kind of high polymer heterogeneous aromatic materials contains hydroxyl, carboxyl, phenolic hydroxyl and other active groups with black or brown appearance. It has the functions of chelation, complexing, ion exchange, floc, dispersion and adhesion.

Sodium isosaccharinic (ISA) was prepared in our laboratory according to Hagberg et al. . 2.1.2. Slag preparation. The steel slag was provided by Outokumpu, Avesta, Sweden and originated from the production of stainless steel from scrap metal recycling.
Stainless steel slag is generated in large quantities during the steel refining process and is commonly used in road paving, as a building material and for cement production. Stainless steel slag is rich in Ca, Mg, Si, Fe, and other elements and has been used for soil improvement and as a fertilizer in agriculture (Wang and Cai 2006). Stainless ...
Humic acid (HA) is a biopolymer formed from degraded plants, making it a ubiquitous, renewable, sustainable, and low cost source of biocarbon materials. HA contains abundant functional groups, such as carboxyl-, phenolic/alcoholic hydroxyl-, ketone-, and quinone/hydroquinone (Q/QH2)-groups. The presence of Q/QH2 groups makes HA redox active and, accordingly, HA is a candidate material for ...
