Physical activation of carbon residue from biomass gasification: Novel sorbent for the removal of phosphates and nitrates from aqueous solution

TL;DR: In this article, carbon residue obtained as a byproduct from wood gasification process was employed as a precursor for preparing adsorbent by physical activation, and the optimal pH and initial concentrations for phosphate and nitrate removal were determined.
Journal ArticleDOI

Simultaneous removal of Ni(II), As(III), and Sb(III) from spiked mine effluent with metakaolin and blast-furnace-slag geopolymers.

TL;DR: The results indicate that geopolymer technology could offer a simple and effective way to turn blast-furnace slag to an effective sorbent with a specific utilization prospect in the mining industry.
Journal ArticleDOI

Application of alkali-activated materials for water and wastewater treatment: a review

TL;DR: Alkali-activation (or geopolymer) technology has gained a great deal of interest for its potential applications in water and wastewater treatment during the last decade as mentioned in this paper, and a comprehensive evaluation of the rapidly growing prospects of alkali activation technology in water-and wastewater treatment is presented in this paper.
Journal ArticleDOI

Sulphate removal over barium-modified blast-furnace-slag geopolymer

TL;DR: The novel modification method of geopolymer material proved to be technically suitable in achieving extremely low concentrations of SO4(2-) (<2mgL(-1)) in mine effluents and the Sips model showed the best fit.
Journal ArticleDOI

Chemically activated carbon residue from biomass gasification as a sorbent for iron(II), copper(II) and nickel(II) ions

TL;DR: In this article, the authors investigated the possibility of the utilization of carbon residue from biomass gasification process with and without chemical activation as a low cost sorbent for iron(II), copper (II) and nickel(II) ions from an aqueous solution.
