Green Synthesis Polyvinylalcohol@Go@Zif-67: An Efficient Mof Composite For Effective Mg Dye Removal

Organic dyes contain toxic, mutagenic and carcinogenic compounds that are used in various industries such as textiles, paper, wool, cosmetics and printing. discharge of dye effluents into water resources is a serious threat to aquatic life and the environment. metal-organic frameworks (mofs) have been compared to other common attractions of researchers due to their characteristics such as surface area and high adsorption capacity, adjustable porosity, crystal structure and high stability. in this study, in order to investigate the adsorption of malachite green (mg) dye from aqueous media, synthesis of graphene oxide (go) based on metal organic frameworks cobalt with polyvinyl alcohol (pva) polymer substrate (pva@go@zif-67) by green synthesis method performed at ambient temperature. ftir and xrd were performed to characterize the physical characteristics and nature of the adsorbent. also, the effect of different parameters on the adsorption process including ph, pollutant initial concentration, adsorbent dose and contact time was investigated. maximum removal efficiency and adsorption capacity under optimal conditions for dye mg were 97.21% and 324 mg/g, respectively

Organic dyes contain toxic, mutagenic and carcinogenic compounds that are used in various industries such as textiles, paper, wool, cosmetics and printing. Discharge of dye effluents into water resources is a serious threat to aquatic life and the environment. Metal-organic frameworks (MOFs) have been compared to other common attractions of researchers due to their characteristics such as surface area and high adsorption capacity, adjustable porosity, crystal structure and high stability. In this study, in order to investigate the adsorption of malachite green (MG) dye from aqueous media, synthesis of graphene oxide (GO) based on metal organic frameworks cobalt with polyvinyl alcohol (PVA) polymer substrate (PVA@GO@ZIF-67) by green synthesis method performed at ambient temperature. FTIR and XRD were performed to characterize the physical characteristics and nature of the adsorbent. Also, the effect of different parameters on the adsorption process including pH, pollutant initial concentration, adsorbent dose and contact time was investigated. Maximum removal efficiency and adsorption capacity under optimal conditions for dye MG were 97.21% and 324 mg/g, respectively
