Water pollution has jeopardized human health, and a safe supply of drinking water been recognized as worldwide issue. The increase in the accumulation heavy metals from different sources led to search for efficient environmentally friendly treatment methods materials their removal. Natural zeolites are promising removing contaminating water. It is important know structure, chemistry, performance removal water, natural design processes. This review focuses on critical analyses application distinct adsorption specifically, arsenic (As(III), As(V)), cadmium (Cd(II)), chromium (Cr(III), Cr(VI)), lead (Pb(II)), mercury(Hg(II)) nickel (Ni(II)). reported results heavy-metal by summarized, chemical modification acid/base/salt reagent, surfactants, metallic reagents analyzed, compared, described. Furthermore, adsorption/desorption capacity, systems, operating parameters, isotherms, kinetics were described compared. According analysis, clinoptilolite most applied zeolite remove metals. effective As, Cd, Cr, Pb, Hg, Ni. Additionally, an interesting fact variation between geological origins regarding sorption properties capacities suggesting that regions world unique.

Metal–organic frameworks (MOFs) based nanofiber architectures for the removal of heavy metal ions

RSC Advances, Journal Year: 2022, Volume and Issue: 12(3), P. 1433 - 1450

Published: Jan. 1, 2022

Environmental heavy metal ions (HMIs) accumulate in living organisms and cause various diseases. Metal-organic frameworks (MOFs) have proven to be promising effective materials for removing from contaminated water because of their high porosity, remarkable physical chemical properties, specific surface area. MOFs are self-assembling or clusters with organic linkers. Metals used as dowel pins build two-dimensional three-dimensional frameworks, linkers serve carriers. Modern research has mainly focused on designing MOFs-based improved adsorption separation properties. In this review, the first time, an in-depth look at use nanofiber HMIs removal applications is provided. This review will focus synthesis, recent advances provide understanding opportunities challenges that arise synthesis future MOFs-nanofiber composites decorated nanofibers possess rapid kinetics, a capacity, excellent selectivity, good reusability. addition, substantial capacities due interactions between target functional binding groups highly ordered porous structure.
