Removal of heavy metal ions from wastewater: a comprehensive and critical review

npj Clean Water, Год журнала: 2021, Номер 4(1)

Опубликована: Июль 8, 2021

Abstract Removal of heavy metal ions from wastewater is prime importance for a clean environment and human health. Different reported methods were devoted to removal various sources. These could be classified into adsorption-, membrane-, chemical-, electric-, photocatalytic-based treatments. This paper comprehensively critically reviews discusses these in terms used agents/adsorbents, efficiency, operating conditions, the pros cons each method. Besides, key findings previous studies literature are summarized. Generally, it noticed that most recent have focused on adsorption techniques. The major obstacles ability remove different ion types concurrently, high retention time, cycling stability adsorbents. Even though chemical membrane practical, large-volume sludge formation post-treatment requirements vital issues need solved Fouling scaling inhibition lead further improvement separation. However, pre-treatment periodic cleaning membranes incur additional costs. Electrical-based also efficient; however, industrial-scale separation needed addition tackling issue formation. Electric- still less mature. More attention should drawn using real wastewaters rather than synthetic ones when investigating metals removal. Future research focus eco-friendly, cost-effective, sustainable materials methods.

A Review on Heavy Metal Ions and Containing Dyes Removal Through Graphene Oxide‐Based Adsorption Strategies for Textile Wastewater Treatment

The Chemical Record, Год журнала: 2021, Номер 21(7), С. 1570 - 1610

Опубликована: Фев. 4, 2021

Abstract Textile wastewater heavy metal pollution has become a severe environmental problem worldwide. Metal ion inclusion in dye molecule exhibits bathochromic shift producing deeper but duller shades, which provides excellent colouration. The ejection of massive volume containing ions such as Cr (VI), Pb (II), Cd (II) and Zn metal‐containing dyes are an unavoidable consequence because the textile industry consumes large quantities water all these chemicals cannot be combined entirely with fibres during dyeing process. These high concentrations effluents interfere natural resources, cause toxicological implications on environment dramatic impact human health. This article reviewed various types their from entryway to wastewater, then briefly explored effects health environment. Graphene‐based absorbers, specially graphene oxide (GO) benefits ordered structured, specific surface area, flexible functionalization options, indispensable realize performance removal. exceptional adsorption properties graphene‐based materials support position ubiquity our everyday lives. collective representation wastewater‘s effective remediation methods is discussed focused GO‐based methods. Understanding critical regarding established portfolio for removal also discussed. Various heavy‐metal pollutant effect, ways remove role adsorbent including demand, perspective, limitation, relative scopes elaborately review.
