Preparation and characterization of immobilized [A336][MTBA] in PVA–alginate gel beads as novel solid-phase extractants for an efficient recovery of Hg (II) from aqueous solutions

Exploring new DGT samplers containing a polymer inclusion membrane for mercury monitoring

“…In sum, each membrane was able to adsorb about 0.05 ng Hg g −1 during a deployment time of 3 h. Thus, these results showed that even though TOMATS is entrapped into a polymeric matrix, this IL is a suitable extractant for Hg. It is postulated that the adsorption of Hg(II) can occur via the interaction of both the deprotonated carboxylic group and the S atom of the thiol group (Zhang et al 2011).…”

Encapsulation of Cyanex 302 with Alginate for Palladium Recovery

“…This study focuses on the encapsulation of Cyanex 302 (bis(2,2,4‐trimethylpentyl) monothiophosphinic acid) in mononuclear (N) calcium alginate gel beads. The conventional process (matrix‐type encapsulation, M) consists of the mixing of the extractant with alginate solution making an emulsion before dropping the mixture into an ionotropic gelation solution (i.e., CaCl 2 , for example) . Various shapes of microcapsules such as granules, fibers and films have been prepared .…”

Brown algae based new sorption material for fractional recovery of molybdenum and rhenium from wastewater

“…Considering the viewpoint of sustainable development and comprehensive utilization of resources, biosorption has a promising prospect and a wide application due to its high removal efficiency, low cost, mild operating conditions and good performance over other conventional treatment processes in the removal and recovery of heavy metal ions from wastewater [3][4][5][6][7][8][9]. It is reported that many large and dominant genus Laminaria japonica algae are found predominantly at patchy or dense regions, while monospecific and belt-like algae are found on rocky shores in temperate to boreal waters [10].…”
