Chemical and spectroscopic analysis of olive mill waste water during a biological treatment [PDF]

, 2007
The treatment of olive mill waste water was studied on the laboratory scale. Physico–chemical analyses showed the final products had a mean pH of 5.4 without neutralisation and 5.7 when lime was added to the process.

Fe(II)/Chlorine‐Driven Advanced Oxidation of Textile Dyes in a Tubular Microreactor: Continuous‐Flow Performance and Matrix Effects

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The Fe(II)/chlorine system has emerged as a promising advanced oxidation technology for water treatment, yet its application in continuous‐flow systems remains unexplored. This study presents the first comprehensive investigation of the Fe(II)/chlorine process in a tubular microreactor, a setup that significantly enhances mass transfer and ...

Adsorption Characteristics and Mechanisms of Dibutyl Phthalate on Nanomaterials

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Dibutyl phthalate (DBP) is a widely used plasticizer whose environmental release poses significant risks to ecosystems and human health. This study systematically investigated DBP adsorption on three common nanomaterials—titanium dioxide nanoparticles (n‐TiO2), multiwalled carbon nanotubes (MWCNTs), and carboxylated MWCNTs (MWCNTs‐COOH)—using ...

Mechanisms of goethite dissolution in the presence of desferrioxamine B and Suwannee River fulvic acid at pH 6.5 [PDF]

, 2013
Siderophores are Fe3+ specific low MW chelating ligands secreted by microorganisms in response to Fe stress. Low MW organic acids such as oxalate have been shown to enhance siderophore mediated dissolution of Fe3+ oxides.

Carbon‐Negative Upcycling of Sewage Sludge into Superiorly Stable Gel Via Liquid‐Phase Utilization Strategy for Water‐Remediation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work developed a low‐temperature sludge hydrothermal coupled with gel crosslinking strategy which could upgrade the waste liquid generated from sewage sludge hydrothermal treatment into the hydrothermal‐liquid‐gel. The inventive hydrothermal‐liquid‐gel exhibited the enhanced pollutant removal capability, high synthetic stability, and superior ...
