Topic:
Water treatment
In the modern society, the problem of the treatment of natural and wastewater resources and their management, is becoming very important.
Of particular interest is the definition of adequate and sophisticated procedures for the treatment of natural and wastewater resources, regardless of whether...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

Removal of heavy metals from sewage sludge using combined hydrothermal pretreatment and chelate extraction
(Corresponding) Usťak S., Muňoz J.
Topic:
Wastewater treatment
The removal of heavy metals from sewage sludge using the combined influence of hydrothermal pretreatment and chelate extraction was tested. The classical method of batch extraction with chelates and the advanced hydrothermal pretreatment (HTP) extraction process with chelates were compared. Both...Read more

The comparison of sediment quality in the rivers the Eastern Slovakia by Potential ecological risk index
(Corresponding) Singovszka E., Balintova M.
Topic:
Heavy metals in the environment
The current pollution of sedimentary environment is very serious and exceeds load capacity limit and it is influenced by other external factors such as climate, hydrodynamic conditions, pH, salinity, Eh, temperature and other. This influences can cause the heavy metals are re-released from the...Read more
Keywords:
heavy metals, pollution, potential ecological risk index
Critical metals were defined as those metals essential for high-tech, medical and defense industry but with low availability due to uneven geographical distribution, thus resulting a high price volatility. The challenge of the future is to assure a stable supply of critical materials and implicitly...Read more
Novel Polyethersulfone (PES) Alpha-Zirconium Phosphate (α-ZrP) Ion Exchange Mixed Matrix Membranes for Effective Removal of Heavy Metals from Wastewater
ABDULKARIM E., IBRAHIM Y., (Corresponding) HASAN S., NADDEO V., BANAT F.
Topic:
Wastewater treatment
In this study, novel polyethersulfone (PES) alpha-zirconium (α-ZrP) ion exchange mixed matrix membranes were fabricated via phase inversion method using nano-sized alpha-zirconium phosphate (α-ZrP-n) and polyvinylpyrrolidone (PVP) as dispersant nano-additives in the dope solution preparation. The...Read more

Effect of heavy metals accumulation on the growth and essential oils content of Rose Geranium (Pelargonium graveolens L.)
Patrolea E., Nikoli T., Loupasaki S., Grigorakis S., (Corresponding) Lydakis-Simantiris N.
Topic:
Heavy metals in the environment
The objective of this study was to investigate the accumulation of Cd, Ni and Pb and their distribution in the aboveground and underground biomass of Rose Geranium (Pelargonium graveolens L.), as well as the effect on the plant’s content and quality of essential oils. For this purpose, a pot...Read more

Red Mud as a Secondary Source of Scarce Metals - Recovery using Red Microalgae
Náhlík V., Čížková M., Singh A., Bišová K., Mezricky D., Rucki M., (Corresponding) Vítová M.
Topic:
Environmental biotechnology and bioenergy
Red mud is a by-product of the production of alumina from bauxite ore. Less than 2% of the red mud produced is currently being reused. The red mud contains a number of residual elements, some at a considerable concentration. The red microalga Galdieria sulphuraria was used to test the accumulation...Read more

Hydro-stratigraphy, Aquifer Characterization and Physiochemical Analysis of District Dera Ghazi Khan Punjab, Pakistan.
(Corresponding) Ullah H., Khalid P., Shah G., Mashwani S., Shafiq W., Din Z.
Topic:
Water treatment
The study area is located in the arid section of Punjab province, Pakistan. The accessibility of freshwater is the main problem in this zone. The area is approximately flat and there are alluvial deposits up to 800 m. Groundwater is not fit for health because of its salinity. Hence, it is essential...Read more
