Biosorption of heavy metals from aqueous solutions onto peanut shell as a low-cost biosorbent
TL;DR: In this paper, the authors investigated the biosorption of Cu(II) and Cr(III) ions from aqueous solutions by peanut shell biomass as a function of initial pH, initial biomass concentration and temperature.

TL;DR: Two-stage ultrafiltration is proposed as a method for separating and purifying rhamnolipid from the culture medium and was capable of reducing surface tension of water down to 28.6 mN/m at critical micelle concentration of 40 mg/l.
Carbon Dioxide Removal in a Membrane Contactor - Selection of Absorptive Liquid/Membrane System
TL;DR: In this paper, the authors demonstrate the application of the membrane contactor for carbon dioxide removal using a single polypropylene capillary membrane and two primary amines (monoethanolamine MEA, diglycolamine DGA), one secondary amine (diethanolamine DEA), one tertiary amine(methyldiethanoline MDEA) were used to prepare absorbate solutions, and the system was investigated for aqueous solutions of amines and for the solutions with piperazine addition.
Removal of cationic dyes from aqueous solutions using microspherical particles of fly ash.
TL;DR: Kinetic studies indicate that sorption on fly ash follows the pseudo-second order kinetics, and research suggests that fly ash could be an appropriate adsorbent for the removal of basic dyes from aqueous solutions.
