Calcined sugar scum as a low-cost adsorbent for dye removal from aqueous solution: Equilibrium, kinetic and modeling

by

Youssef El maguana et al. View all

Solid Waste Management

Batch adsorption experiments have been conducted to investigate the adsorption properties of the calcined sugar scum powder for methylene blue (MB) and methyl orange (MO) as models for cationic and anionic dyes. The kinetic and equilibrium adsorption have been investigated to determine the...

Kheng Soo Tay et al. View all

Innovative environmental solutions

The development of magnetic sorbent for dispersive solid-phase micro-extraction (DmSPE) often requires lengthy multi-step reactions. This research revealed a simplified method for preparing magnetic sorbent for the DmSPE using poly(4-vinylphenol) (PVP). The magnetic sorbent (PVP@MNP) was prepared by...

Organic pollutants removal from oilfield produced water using nano magnetite as adsorbent

by

Ghazi Faisal Naser et al. View all

Water and Wastewater Treatment

The current study investigates the ability of Nano magnetite as an adsorbent to remove organic materials from oilfield-produced water (PW). The effect of several variables on the removal procedure was investigated, such as nano magnetite dose, pH of solution and adsorption period. The adsorbent was...
