Removal of Cu(II) and Pb(II) ions from aqueous solutions by adsorption on sawdust of Meranti wood

Study of Metal Adsorbent Prepared from Tur Dal (Cajanus cajan) Husk: A Value Addition to Agro-waste

“…As the adsorption commenced with time there was exhaustion of adsorption sites with adsorbent. At his stage the phenomenon of migration of Adsorbate from the exterior to the interior sites of the adsorbent particles took the control of adsorption and the adsorption observed was less effective [55,56]. The result agrees with the findings of A.V.…”

Efficacy of Mangrove (Rhizophora Mucronata) Roots Powder in Adsorption of Lead (II) Ions from Aqueous Solutions: Equilibrium and Kinetics Studies

“…Similar results were observed by [16] who worked on rice husks and [17] who worked on treated sawdust of sissoo wood. [18] demonstrated that the adsorption of Pb (II) ions increased linearly as the amount of adsorbent (mixture of activated charcoal and peanut shell) increased from 1.0 g to 3.0 g and became constant from 3.0 g to 5.0 g.…”

Microwave incinerated sugarcane bagasse ash (MISCBA) as a low cost adsorbent for the removal of zinc in aqueous solution

“…Figure 3 shows the plot of the effect of adsorbent dosage on the removal efficiency of zinc. It is evident from the plot that rate of removal increases with an increase in MISCBA dosage, literally this is attributed to the availability of more adsorption sites at increased attentiveness of the adsorbent material with regard to complexation of metal ions (Ahmad et al [16]). Removal percentage of zinc increased from 73.5% to 91.1% with an increase in MISCBA adsorbent at equilibrium condition.…”
