A Review on Heavy Metal Ions and Containing Dyes Removal Through Graphene Oxide-Based Adsorption the Strategies for Textile Wastewater CHEMICAL RECORD Treatment Personal Account DOI: 10.1002/tcr.202000153 A Review on Heavy Metal Ions and Containing Dyes Removal Through Graphene Oxide-Based Adsorption THE Strategies for Textile Wastewater CHEMICAL RECORD Treatment Sasireka Velusamy, Anurag Roy, Senthilarasu Sundaram,* and Tapas Kumar Mallick[a] Abstract: Textile wastewater heavy metal pollution has become a severe environmental problem worldwide. Metal ion inclusion in a dye molecule exhibits a bathochromic shift producing deeper but duller shades, which provides excellent colouration. The ejection of a massive volume of wastewater containing heavy metal ions such as Cr (VI), Pb (II), Cd (II) and Zn (II) and metal- containing dyes are an unavoidable consequence because the textile industry consumes large quantities of water and all these chemicals cannot be combined entirely with fibres during the dyeing process. These high concentrations of chemicals in effluents interfere with the natural water resources, cause severe toxicological implications on the environment with a dramatic impact on human health. This article reviewed the various metal-containing dye types and their heavy metal ions pollution from entryway to the wastewater, which then briefly explored the effects on human health and the environment. Graphene-based absorbers, specially graphene oxide (GO) benefits from an ordered structured, high specific surface area, and flexible surface functionalization options, which are indispensable to realize a high performance of heavy metal ion removal. These exceptional adsorption properties of graphene-based materials support a position of ubiquity in our everyday lives. The collective representation of the textile wastewater‘s effective remediation methods is discussed and focused on the GO-based adsorption methods. Understanding the critical impact regarding the GO-based materials established adsorption portfolio for heavy metal ions removal are also discussed. Various heavy-metal ions and their pollutant effect, ways to remove such heavy metal ions and role of graphene-based adsorbent including their demand, perspective, limitation, and relative scopes are discussed elaborately in the review. Keywords: Adsorption, Graphene Oxide, Heavy metal removal, Textile effluent treatment, Wastewater treatment methods 1. Introduction which increase the demand for clean water.

  • Why Some Migration Conditions for Plastics Are Not Appropriate for Other Fcms
    Why some migration conditions for plastics are not appropriate for other FCMs. Peter Oldring Representing 18 associations directly or indirectly involved in FCMs FIP Network 25th May 2016 Parma 1 Extract from Executive Summary (p9) European Parliament report on 1935/2004 (May 2016) ‘As a general trend, stakeholders who are in favour of further EU level harmonisation recommend that EU specific measures should establish a single standard for analytical (testing) methods, such as composition determination, migration testing, risk assessment, but also specific methods for compliance enforcement, thus ensuring that the relevant FCM is tested by companies and competent authorities across the EU with one and the same method. Furthermore, the EU single standard for analytical (testing) methods should be specific for each FCM, thus reflecting its unique properties and avoiding situations where non-harmonised FCMs are tested with methods developed for harmonised FCMs, which could lead to misleading and debatable test results’ 2 DISCLAIMER . As chair of the 18 associations representing non- plastics, I will try and represent them. The initiative started with CEPE, EMPAC and almost immediately CES silicones joined. Other associations have joined since then. However, I have to understand and work with analytical data, in order to make decisions about and determine the safety of my company’s products. The work is embryonic, associations are still joining and the final format will certainly be different to that initially envisaged. 3 Associations participating in Initiative .
