“…The adsorbed molecules can then be eluted, thereby regenerating the resin to achieve the enrichment, separation and recovery of organic matter in wastewater [ 7 , 8 , 9 ]. For example, Zhu Shiyun et al [ 10 ] used the strong anionic resin Amberlite IRA 402-OH to remove acetaldehyde from petrochemical production wastewater. The acetaldehyde removal efficiency from wastewater was 86%.…”

Polymeric adsorbents with different properties were synthesized via suspension polymerization. Equilibrium and kinetics experiments were then performed to verify the adsorption capacities of the resins for molecules of various sizes. The adsorption of small molecules reached equilibrium more quickly than the adsorption of large molecules. Furthermore, the resins with small pores are easy to lower their adsorption capacities for large molecules because of the pore blockage effect. After amination, the specific surface areas of the resins decreased. The average pore diameter decreased when the resin was modified with either primary or tertiary amines, but the pore diameter increased when the resin was modified with secondary amines. The phenol adsorption capacities of the amine-modified resins were reduced because of the decreased specific area. The amine-modified resins could more efficiently adsorb reactive brilliant blue 4 owing to the presence of polar functional groups.

“…Wang et al [8] efficiently eliminated formaldehyde from water, with up to 99% removal efficiency, using a mesoporous calcium silicate hydrate (CSH). Salehi and Shafie [88] used adsorption to purify water from acetaldehyde by means of strong anionic resins, i.e., AMBERLITE IRA 402-OH, after a pre-treatment with bisulfite. In this way, they obtained an 86% pollutant removal, starting from a concentration of the substance equal to 50 mg/L.…”

Water Purification of Classical and Emerging Organic Pollutants: An Extensive Review

2021

View full text Add to dashboard Cite

The main techniques used for organic pollutant removal from water are adsorption, reductive and oxidative processes, phytoremediation, bioremediation, separation by membranes and liquid–liquid extraction. In this review, strengths and weaknesses of the different purification techniques are discussed, with particular attention to the newest results published in the scientific literature. This study highlighted that adsorption is the most frequently used method for water purification, since it can balance high organic pollutants removal efficiency, it has the possibility to treat a large quantity of water in semi-continuous way and has acceptable costs.
