Photochemical UV/TiO2 treatment of olive mill wastewater (OMW) [PDF]
, 2008 Olive mill wastewater (OMW) was treated by photocatalysis using TiO2 under UV irradiation on the laboratory scale. The chemical oxygen demand, the coloration at 330 nm, and the level of phenols all showed decreases which, after a 24-h treatment, reached ...

TLC Determination of Aquatic Humic Acids
Water Science and Technology, 1992 Humic acids are mostly determined by spectroscopic methods, although they are not accurate enough, because humic acids possess no maximum absorption at any wavelength in the ultraviolet and visible spectrum. In this contribution the accurate and precise method for aquatic humic acids determination, using thin layer chromatography, was worked out ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study successfully prepared magnetic iron/cobalt codoped biochar catalyst (CFSBC) using a one‐step calcination method. The morphology and structure of the material were systematically characterized using SEM, XRD, FTIR, TEM, BET, Raman, VSM, and XPS techniques. The effects of key parameters such as catalyst dosage, peroxymonosulfate (PMS)

Mitigation of GHGs Emission From Soils by a Catalyzed In-Situ Photo-Oxidative Polymerization of Soil Organic Matter [PDF]
, 2010 Agricultural lands under food and bio-energy crops, managed grass and permanent crops including agro-forestry, occupy about 40-50% of the Earth's land surface^1^. In 2005, agriculture accounted for an estimated emission of 5.1 to 6.1 GtCO2-eq/yr (10-

Humic acid removal by electrocoagulation: characterization of aluminum species and humic acid
Desalination and Water Treatment, 2016 In this study, the different aluminum (Al) species generated during electrocoagulation (EC), the humic acid (HA) removal, and the change in HA characteristics were evaluated. The results show that the distribution of monomeric Al species (Ala), medium polymer Al species (Alb), and colloidal or solid Al species (Alc) was dependent on initial pH 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 ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT A new type of thin‐film nanocomposite (TFN) membrane was synthesized by incorporating cellulose nanocrystals (CNCs) into a polyvinyl alcohol (PVA) top layer on a polycarbonate (PC) substrate via dip‐coating. The synthesized TFC and TFN membranes (PC/PVA TFC and PC/PVA‐CNC TFN membranes) were evaluated using contact angle measurement, field ...
