Understanding the adsorption mechanisms and interaction of dye pollutants microplastics in natural water is vital to evaluating potential risks. This review article discusses bibliometric analysis behavior dyes microplastics. The also examined impact environmental (salinity, pH, temperature) physicochemical (particle size active area) factors on uptake by maximum amount Cyan adsorbed onto polyethylene was reported be 2874.4 mg/g. Polystyrene (PS) exhibited highest capacity for aniline (0.060 mg/g) due its surface area 0.7214 m2/g. In 50 % studies microplastics, equilibrium condition reached within 24 h. However, a few cases, achieved 8 days. desorption efficiency malachite green simulated gastric fluid at high temperatures 81.4 %. concentration isotherm their varied widely (5–160 mg/L). According criterion R2 > 0.95, Langmuir demonstrates better fit with data most studies. lowest observed pH 1.5 under same conditions.

Durable Nano‐Flower Structured Foam Coupled with Electrically‐Driven in Situ Aeration Enable High‐Flux Oil/Water Emulsion Separation with Dynamic Antifouling Ability

Small, Journal Year: 2024, Volume and Issue: unknown

Published: April 26, 2024

Abstract The conventional membranes used for separating oil/water emulsions are typically limited by the properties of membrane materials and impact fouling, making continuous long‐term usage unachievable. In this study, a filtering electrode with synchronous self‐cleaning functionality is devised, exhibiting notable antifouling ability an extended operational lifespan, suitable separation emulsions. Compared original Ti foam, in situ growth NiTi‐LDH (Layered double hydroxide) nano‐flowers endows modified foam (NiTi‐LDH/TF) exceptional superhydrophilicity underwater superoleophobicity. Driven gravity, rejection rate over 99% achieved various containing oil content ranging from 1% to 50%, as well oil/seawater flux recovery exceeds 90% after one hundred cycles 4‐h filtration period. enhanced performance realized through “gas bridge” effect during aeration electrochemical anodic oxidation. internal within pores contributes removal foulants. This study underscores potential coupling metal technology, providing paradigm exploration novel membranes.
