Chromium (Cr) exists in aqueous solution as trivalent (Cr3+) and hexavalent (Cr6+) forms. Cr3+ is an essential trace element while Cr6+ a dangerous carcinogenic element, which of great concern globally due to its extensive applications various industrial processes such textiles, manufacturing inks, dyes, paints, pigments, electroplating, stainless steel, leather, tanning, wood preservation, among others. wastewater can be transformed into when it enters the environment. Therefore, research on Cr remediation from water has attracted much attention recently. A number methods adsorption, electrochemical treatment, physico-chemical methods, biological removal, membrane filtration have been devised for efficient removal water. This review comprehensively demonstrated technologies literature date. The advantages disadvantages were also described. Future directions are suggested provide application adsorbents waters.

Zeolites, a group of minerals with unique properties, have been known for more than 250 years. However, it was the development methods hydrothermal synthesis zeolites and their large-scale industrial applications (oil processing, agriculture, production detergents building materials, water treatment processes, etc.) that made them one most important materials 20th century, great practical research significance. The orderly, homogeneous crystalline porous structure zeolites, susceptibility to various modifications, useful physicochemical properties contribute continuous expansion in both large-volume processes (ion exchange, adsorption, separation mixture components, catalysis) specialized ones (sensors). following review knowledge available literature on aims present information methods, selected this aluminosilicates. Special attention is given use agriculture environmental protection.

This study created green multifunctional geopolymeric sorbent material with strong cationic dye adsorption capacity and superior mechanical strength to broaden lead sludge (LS)-based geopolymer applications. In this study, two sorbents (Go G) were fabricated using slag blended 0 50 wt.% LS, respectively activated 6 NaOH. The Go G specimens normally cured for up 28 days, while hydrothermally at different steam-pressures modify/improve histological characteristics as well resistance. selected characterized via XRD, FTIR, TGA/DTG, XPS, N2-adsorption/desorption SEM/EDX techniques. G/5bar's high may be due the production of CSH, CAH, CASH, NASH, which formed a fine mesoporous zeolitic structure highest BET-surface area (64.55m2/g) lowest BJH-maximum pore diameter (9.68nm). maximum MB synthesized adsorbent was 230.4 mg/g.
