One-step Synthesis of TiO2/ZnO Nanocomposites by Refluxing Methods for Photochemical Degradation of Humic Acid
(Corresponding) Fadillah G., HIdayat R., (Corresponding) Wahyuningsih S.
Topic:
Nanomaterials in the environmnents applications and effects
Synthesis of TiO2/ZnO nanocomposites (TZN) through one-step refluxing method for photochemical degradation of humic acid (HA) in aqueous solution has been studied. Titanium isopropoxide (TTIP) and ZnSO4.7H2O were used as a starting material under base solution at 120 oC for 24 hours. TZN materials...Read more
Thermal degradation of perfluorooctanoic acid (PFOA)
(Corresponding) Stockenhuber S., Weber N., Dixon L., Lucas J., Grimison C., Bennett M., Stockenhuber M., Mackie J., Kennedy E.
Topic:
Soil and groundwater contamination and remediation
Per - and polyfluoroalkyl substances (PFAS) are a group of environmental contaminants, that are dispersed throughout the world. A number of areas have been affected by their persistence and biomagnification. PFAS remediation of contaminated material requires extensive knowledge of the species...Read more

Feasibility of combined anaerobic-aerobic system for textile wastewater contained C. I. Acid Red 88 dye treatment: HRT effects and functional resilience
(Corresponding) Gadow S., Li Y.
Topic:
Wastewater treatment
An integrated continuous anaerobic–aerobic system has been employed as the treatment for synthetic textile wastewater contained C. I. Acid Red 88 dye. A laboratory scale of upflow anaerobic sludge bed (UASB) flowed by activated treatment was operated at hydraulic residence time (HRT) of 24, 12, 6,...Read more

Biotechnological conversions of crude glycerol, residue deriving from biodiesel production facilities, by strains of the yeast Yarrowia lipolytica
(Corresponding) Papanikolaou S., Diamantopoulou P., Sarris D., Aggelis G.
Topic:
Environmental biotechnology and bioenergy
Aim of the present study was to assess the ability of four Yarrowia lipolytica strains (ACA-DC 50109, LFMB Y-20, ATCC 20460 and LMBF Y-45) to grow on biodiesel-derived crude glycerol, the principal residue-stream deriving from biodiesel manufacture. Initial trials were carried out in shake-flasks...Read more
A new sustainable approach in recovering Cobalt from “hard metal” production by-products
Amadou O., DE GAUDENZI G., MARCHESELLI G., PIREDDA M., (Corresponding) SERPE A.
Topic:
Hazardous waste management
The present work shows the capability of Maleic Acid solutions to tune the amount of Co in cemented carbide-based recovery powders with a Co content exceeding the threshold (10% Co) for industrial manufacturing in Hard Metal production and required by safety regulations. Maleic acid solutions react...Read more

Biological activity of flufenamic acid and synthesized derivates (PFCs) that may occur in the environment
(Corresponding) Šilha D., Šilarová P., Weidlich T.
Topic:
Emerging pollutants
Polyfluorinated compounds (PFCs) are used in the field of pharmaceuticals, pesticides, impregnating agents, etc. These are predominantly compounds that are difficult to degradate in the environment, and therefore are highly persistent. Many these compounds are known to have toxic effects and thus a...Read more
Impact on the effect of acetic acid in its aqueous forms on environments and its separations by solvent extraction method- A review
(Corresponding) Sofiya K., Karunanithi B.
Topic:
Emerging pollutants
Acetic acid is one of the top twenty commodities used in various industrial processes. Removal of acetic acid in its aqueous forms is a significant problem, and it cannot be discarded directly to the environment because of its acidity nature. The separation of acetic acid from its aqueous phase is...Read more

High FAME yield Biodiesel from microalgae through nanocatalytic transesterification process.
Mittal V., (Corresponding) Ghosh U.
Topic:
Environmental biotechnology and bioenergy
Biodiesel production from microalgae is significantly important when reserves of petro-diesel are depleting, and utilization of vegetable oil-based fuel leads to food scarcity. The rapid growth and high lipid content of microalgae is an ideal feedstock for biodiesel production. The use of...Read more

Peracetic acid disinfection: An effective way to reduce antibiotics resistant bacteria from raw hospital wastewater
(Corresponding) Chhetri R., Sanchez Urbina D., Lindholst S., Rickers C., Elkær T., Gade H., Skaarup J., Andersen H.
Topic:
Wastewater treatment
Risk of infection from antibiotic resistant bacteria from wastewater to the workers in the plant can be reduced by disinfecting wastewater. Peracetic acid (PAA) was used to disinfect the raw wastewater from hospital in pilot scale experiment. Batch experiment was conducted in parallel to confirm...Read more
AliCy as Extractant to Remove Iron from Copper-Free Extreme AMD for Further Extraction of Zinc
Nobahar A., Melka A., Neves L., Carlier J., (Corresponding) Costa M.
Topic:
Wastewater treatment
A previous work showed that copper can be specifically extracted from acid mine drainage (AMD) classified as high-acid and extreme-metals (pH 1.19, ~63 g/L Fe, ~6.5 g/L Al, ~5.3 g/L Cu, ~1.9 g/L Zn and ~0.1 g/L Mn), using 30% (v/v) Acorga M5640 in Shell GTL (a kerosene like solvent) as extractant...Read more
