IMPREGNATED RESINS AS NOVEL SORBENTS FOR REMOVAL OF TOXIC METAL IONS FROM AQUEOUS SOLUTIONS
(Corresponding) Zawierucha I., Nowik-Zajac A., Kozlowski C.
Topic:
Wastewater treatment
The adsorption/solid phase extraction (SPE) processes are the most attractive methods for effective removal of metals ions from different aqueous solutions. In SPE procedure, the choice of appropriate adsorbent is a critical factor to obtain full recovery and high enrichment factor.
For this...Read more

REMOVAL OF TOXIC METAL IONS THROUGH POLYMER INCLUSION MEMBRANES CONTAINING MACROCYCLIC LIGANDS AS CARRIERS
(Corresponding) Nowik-Zajac A., Zawierucha I., Kozlowski C.
Topic:
Wastewater treatment
More strict environmental regulations on the discharge of toxic metals require developing various technologies for their removal from polluted streams. The separation of toxic metal ions using immobilized membranes with doped ligands, due to their high selectivity and removal efficiency, increased...Read more

RECOVERY AND SEPARATION OF VALUABLE METALS (COPPER AND ZINC) FROM ACIDIC MINE WATERS BY ION-EXCHANGE RESINS
(Corresponding) Vecino X., Reig M., López J., Valderrama C., Gibert O., Cortina J.
Topic:
Water and wastewater reuse
Mining wastewaters, containing heavy metals such as copper (Cu) and zinc (Zn), have a huge impact on the environment due to they are not biodegradable and tend to bioaccumulate in plants or living organisms. Therefore, in this work the performance of ion-exchange and solvent-impregnated resins were...Read more

Biorecovery of metal sulfides from leachates obtained through zinc-carbon battery recycling
(Corresponding) Retka J., Uhrynowski W., Zhendong Y., Karczewska-Golec J., Bajda T., Drewniak L., Debiec-Andrzejewska K.
Topic:
Solid waste management
One of the most commonly used methods of recycling of spent zinc-carbon batteries is hydrometallurgical leaching with sulfuric acid. The technology is highly efficient and enables the recovery of the majority of deposited metals. Unfortunately it also generates leachates that remain after the...Read more

Bioleaching for metal recovery from telecoms switchboard
Baniasadi M., (Corresponding) Farnaud S., Graves J., Renshaw D., Moris S.
Topic:
Electric and electronic waste
Printed circuit boards (PCBs) are a necessity for electronic equipment to function especially in the telecommunications industry. From a PCB for broadcasting networks to PCBs for office communications they are what makes electronic communications equipment operate. The sophistication possible with...Read more
Sources and transfer of Cu, Hg and Pb into marine food webs using innovative tracers (metal stable isotopes, trophic markers): results of a pilot study in a French coastal area
(Corresponding) Chouvelon T., Araujo D., Bouchoucha M., Briant N., Bruzac S., Crochet S., Knoery J., Ponzevera E., Rozuel E., Sireau T., Thomas B., Amouroux D., Bérail S., Brach-Papa C.
Topic:
Heavy metals in the environment
Copper (Cu), mercury (Hg) and lead (Pb) are elements and contaminants of historical and emerging concerns in coastal environments. Although Cu is considered essential for living organisms, it is bioactive in a narrow range of optimal concentrations. Hg and Pb have no known biological role and are...Read more
Long-term impact of use of treated wastewater on accumulation of metals in soil.
(Corresponding) Elsergany M., KARKAIN R., DIAMADAPOULOS E., Moussa M.
Topic:
Water and wastewater reuse
The aim of this paper is to assess the environmental risks associated with the wastewater reuse with respect to six metals; cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) in the city of Dubai. Treated Sewage Effluent (TSE) is used for landscape irrigation. Samples of...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

Exploitation of Treated Municipal Wastewater in Arid Regions Irrigation for Volatile Oils Production
Radwan S., (Corresponding) Ashour E.
Topic:
Water and wastewater reuse
To avoid any contamination risk of edible crops, the safety use of treated municipal wastewater is growing industrial non-food crops such aromatic plants to produce volatile oils for manufacturing soaps, cosmetics and perfumes, etc. Two field experiments were conducted in a sandy soil in western...Read more

Increasing the recovery of automobile shredder residue (ASR) through assimilation to a solid recovered fuel (SRF): the results of a feasibility study
(Corresponding) Ruffino B., Minardi M., Guglielmino M., Bonino F., Zanetti M.
Topic:
Energy technologies and sustainability
This study analyzes the possibility of assimilating some fractions extracted from the shredder light fraction (SLF) to a solid recovered fuel (SRF). Italian Ministerial Decree D.M. 22/2013 fixes the criteria for the assimilation in the compliance of three parameters (heating value and chlorine and...Read more
