Journal ArticleDOI
Adsorption characteristics for the removal of a toxic dye, tartrazine from aqueous solutions by a low cost agricultural by-product
TL;DR: In this paper, the effect of the parameters such as pH, initial dye concentration and temperature on the removal of an anionic dye, tartrazine, from aqueous solutions has been investigated.
Journal ArticleDOI
Biomass-derived biosorbents for metal ions sequestration: Adsorbent modification and activation methods and adsorbent regeneration
TL;DR: In this article, the authors provide a comprehensive appraisal of the equilibrium modeling of a number of biosorption processes as well as the structural, chemical and morphological modifications and activation of biosorbents.
Journal ArticleDOI
Polymer functionalized nanocomposites for metals removal from water and wastewater: An overview
Giusy Lofrano,Maurizio Carotenuto,Giovanni Libralato,Rute F. Domingos,Arjen Markus,Luciana Dini,Ravindra Kumar Gautam,Daniela Baldantoni,Marco Rossi,Sanjay K. Sharma,Mahesh Chandra Chattopadhyaya,Maurizio Giugni,Süreyya Meriç +12 more
TL;DR: These nanoparticle-matrix materials are of great interest for metals and metalloids removal thanks to the functional groups of the polymeric matrixes that provide specific bindings to target pollutants.
Book ChapterDOI
CHAPTER 1:Contamination of Heavy Metals in Aquatic Media: Transport, Toxicity and Technologies for Remediation
TL;DR: In this paper, a comprehensive appraisal over the transport, toxicity and development of removal technologies is given along with their merits and demerits, and several low-cost biosorbents have been synthesized and successfully applied to remove toxic metals and metalloids from wastewater.
Journal ArticleDOI
Adsorption characteristics of alumina nanoparticles for the removal of hazardous dye, Orange G from aqueous solutions
Sushmita Banerjee,Shikha Dubey,Ravindra Kumar Gautam,Mahesh Chandra Chattopadhyaya,Yogesh Sharma +4 more
TL;DR: In this article, the effect of various important parameters on dye removal was examined and adsorption was found to be highly pH dependent and maximum removal of 98.4% was observed at pH 2.5.
