Experimental study of the removal of copper from aqueous solutions by adsorption using sawdust

Experimental Study to Remediate Acid Fuchsin Dye Using Laccase-Modified Zeolite from Aqueous Solutions

“…At higher concentrations, the competition for the surface active sites is high and, consequently, lower sorption rates are obtained. The equilibrium adsorption capacity (q e ), however, increased with an increase in initial AFD concentration because a large number of AFD ions are adsorbed at the available adsorption sites [47][48][49].…”

Biosorptive Removal of Cu(II) from Aqueous Solutions by Using Carissa carandas and Syzygium aromaticum

“…As a result of the expensive nature of the use of the conventional methods, in recent years, attention has been focused on the potential of Green Chemistry for removal of copper from aqueous solution using adsorbents derived from low-cost materials. Many researchers have used low-cost materials 17 as a viable biosorbent for copper(II) removal, namely, rice husk 18-20 , sugarcane, banana peel [21][22] , peanut shells 23 , activated sludge 24 , brewery biomass 25 , ipomoea carnea 26 , cassava 27 , tea waste 28 fly ash 29 , tree fern 30 , cashew nut shell 31 , mansonia wood sawdust 32 , mushroom biomass 33 , activated carbon [34][35], pomegranate pulp 36 , leaves of neem 37 , wheat straw [38][39] , sawdust (Dalbargiasissoo) 40 , pine fruit 41 , orange peel 21,42 and pine cone shell 43 .…”

Preparation and characterization of biosorbents and copper sequestration from simulated wastewater

“…It has been reported that excessive intake of copper by humans may lead to severe mucosal irritation, hepatic and renal damage, capillary damage, gastrointestinal irritation and central nervous system irritation (Larous et al 2005). Increasingly stringent discharge limits for heavy metals and their widespread uses threatening presence at hazardous waste sites have accelerated the search for advanced and economically attractive treatment technologies for their removal.…”
