Design and application of thiourea modified D301 resin for the effective removal of toxic heavy metal ions

Highly efficient sorption of molybdenum from tungstate solution with modified D301 resin

“…27,28 It is reported that some resin and extractant mixtures can greatly improve the sorption capacity and the selectivity of the resin. 29 In addition, some heavy rare earth have been recovered with P227-impregnated resins system, 17 Cr(vi) have been recovered with poly-epichlorohydrin-dimethylamine (EPIDMA) modied D301 resin. 30 Hence, in order to improve the sorption efficiency of D301 resin, a mixture of D301 resin and TOA was explored to separate and recovery molybdenum from tungstate solution in the present study.…”

A multiple model approach for evaluating the performance of time-lapse capsules in trapping heavy metals from water bodies

“…The timelapse capsules were surrounded by a cylindrical polyethylene mesh to increase the mechanical durability. It is noted that the adsorption by ion-exchange resins has been used for various applications, such as removal of heavy metals, 4,5 removal of peruoroalkyl substances, 6 removal of metal complexed azo dyes, 7 nutrient recovery from urine, 8 and precious metal recovery from electrical and electronic wastes. 9,10 The developed time-lapse capsules could be readily deployed in monitoring works and could serve as concentrators of heavy metals from a water body.…”

Wild Heterotrophic Nitrifying Strain Pseudomonas BT1 Isolated from Kitchen Waste Sludge Restores Ammonia Nitrogen Removal in a Sewage Treatment Plant Shocked by Thiourea

“…Thiourea is widely used in various industries [1,19,22], for example, as a metal scavenger in the metallurgical industry and in printed metal board manufacturing [17,23]) and as a synthetic intermediate in the pharmaceutical and resin industries [10,16]. These industries often generate large amounts of thiourea-containing wastewater [11].…”
