Metal oxide semiconductors are of great technological importance in environmental remediation because they can generate charge carriers when stimulated with the required energy. ZnO and TiO2, both well-known photocatalysts, were taken into account for our study because of their practical, inexpensive, non-toxic behavior, high photosensitivity, stability, and increased activity towards photocatalytic degradation of organic pollutants.

Wine sector is very important agri-food branch and represent a relevant segment of the worldwide economy. Several studies have evaluated the environmental profile of grape and wine production using life cycle assessment (LCA). During viticulture practices and wine production a considerable quantity of residues is generated: woody waste from pruning process, stalks from de-stemmed grapes, […]

Abdel BOUGHRIET, Nicole POUMAYE, Oscar ALLAHDIN, Michel WARTEL; Kinetic and diffusional aspects of heavy metals adsorption onto zeolitized brick; Advanced Materials and Technologies Environmental Sciences; 2019:3(4): 281-297

A kinetic study of the removal of Cd2+, Co2+, Fe2+, Mn2+, Ni2+, Pb2+ and Zn2+ cations from single component solution by zeolitized brick was undertaken at 298 K under batch conditions. Kinetic data were well explained by a pseudo-second-order rate model. Correlation analysis showed that the metal affinity sequence of the activated brick followed the […]

Polymer flooding is an excellent candidate for enhancing recovery factor through increasing volumetric sweep efficiency. Polymers are generally used to increase the viscosity of the displacing fluid. These chemicals significantly reduce the mobility ratio between the displacing and displaced fluid. This paper aims to provide a comprehensive review about enhanced oil recovery (EOR) methods, pros […]

Valerii BARBASH, Olha YASHCHENKO. Developing the technology of obtaining microcrystalline cellulose from flax fibers; Advanced Materials and Technologies Environmental Sciences; 2019:3(2): 247-254

The process of obtaining microcrystalline cellulose from flax fibers, which involves obtaining organosolv pulp in an environmentally safer method, followed by its treatment with a mixture of acids and hydrolysis, is explored. The proposed technology allows reducing the number of stages of processing plant materials, eliminating the use of more expensive chemicals and reducing the […]

Currently, world population is 7,62 billion people and thus the need for safe, clean water is imperious. World Health Organization/ UNICEF carried-out studies that almost 1,5 billion people are in danger because they do not have access to safe potable drinking water and nearly 3 billon people lack access to clean water. Studies suggest that […]

The adsorption of sodium ions onto Amberjet 1500H synthetic ion exchange resin was studied. The study was conducted by a batch method to determine equilibrium and kinetic studies using synthetic solution of 5.3 pH and Na concentration ranged from 10 to 20 mg/L. The experimental isotherm data were analyzed using Temkin and Dubinin-Radushkevich equations. Adsorption […]

Wei YAN, Linping KUAI; Comparison of effects of iodine-131 and uranium on Vibrio Qinghaiensis sp. Q67; Advanced Materials and Technologies Environmental Sciences; 2018:2(2):199-205

Effects of Na131I and UO2(NO3)2 on Vibrio Qinghaiensis sp. Q67 (a freshwater luminescent bacterium) were studied in the paper. Relative luminosity (Irel) was used as the tested physiological parameter. About Na131I solution, Four radioactive concentrations were designed. Irel was fluctuated as the activity under 1000Bq/ml and varied irregularly, while three successive stages in the bioluminescent response […]

Three different zeolitic materials derived from coal combustion by-products (CCBs) were used to treat local coal ash landfill leachate at the same power plant. The zeolitc materials properties were characterized in terms of mineralogical composition (XRD), chemical composition (XRF), total carbon content, morphological analysis (SEM), specific surface area (BET method), cation exchange capacity (CEC), loss […]
