Removal of salts and dyes by low ZnAl2O4–TiO2 ultrafiltration membrane deposited on support made from raw clay

Preparation and characterization of novel ceramic membranes for micro-filtration applications

“…At sintering temperature, boric acid increases the mechanical strength by the formation of metallic metaborates and also acts as colloidal agent to improve dispersion properties of the inorganic materials and create homogeneity in the membrane structure. Sodium metasilicate acts as a binder by providing silicate bonds between the elements to induce higher mechanical strength in the membrane [8,9].…”

Elimination of dyes from aqueous solutions using iron oxides and chitosan as adsorbents: a comparative study

“…The adsorption of cationic and anionic dyes on hydrated zirconium oxide or iron oxides has been reported. 13 These materials are common as adsorbents by their limited solubility and their amphoteric properties. However, sometimes these oxides present low surface area and this aspect is a problem to resolve.…”

Optimization of Fenton-biological treatment scheme for the treatment of aqueous dye solutions

“…Due to above problems associated with biological treatment of azo dyes, several researchers have focused on various physicochemical methods like chemical precipitation [21], adsorption [22,23], membrane processes [24], electrochemical coagulation [25], advanced oxidation processes viz. catalytic oxidation [26,27], ozonation [28], radiolysis [29], sonochemical oxidation [27,28] and Fenton's oxidation [29][30][31][32] for treatment azo dye containing wastewater.…”
