The presence of high concentrations heavy metals (potentially toxic elements) in water bodies generates serious environmental issues and health problems that led to a dramatic increase wastewater treatment costs. Therefore, it is imperative develop low-cost efficient technologies for removing these contaminants from wastewater. Membrane processes are advanced techniques ultrafiltration membrane (UF) has some advantages over other membranes as requires low pressure perform However, the UF separates mainly by size exclusion mechanism, resulting poor decontamination performance potentially elements susceptibility fouling. often affected organic biofouling. Hence, researchers still looking forward developing new types will make them more effective removal overcome obstacle This review aims provide an overview application element through bibliometric analysis literature review. incorporation various organic, inorganic, carbon-based, composite-based nano-materials into polymers such zeolites, metal–organic frameworks (MOFs), graphene oxide (GO) gave encouraging results water. Moreover, this discusses mechanisms fouling how different can be used control it. In end, all materials evaluated compared based on their efficiency, toxicity, simplicity preparation, popularity, cost efficiency overall critical view work done area. Also, major challenges limitations use provided which help set direction future research.

Unveiling the Growth of Polyamide Nanofilms at Water/Organic Free Interfaces: Toward Enhanced Water/Salt Selectivity

Environmental Science & Technology, Journal Year: 2022, Volume and Issue: 56(14), P. 10279 - 10288

Published: July 8, 2022

The permeance and selectivity of a reverse osmosis (RO) membrane are governed by its ultrathin polyamide film, yet the growth this critical film during interfacial polymerization (IP) has not been fully understood. This study investigates evolution nanofilm at aqueous/organic interface over time. Despite thickness remaining largely constant (∼15 nm) for IP reaction time ranging from 0.5 to 60 min, density increased 1.25 1.36 g cm–3 due continued between diffused m-phenylenediamine dangling acyl chloride groups within formed film. led simultaneous increase in crosslinking degree (from 50.1 94.3%) healing nanosized defects, resulting greatly enhanced rejection 99.2% NaCl without sacrificing water permeance.
