In this paper, original thermosensitive copolymers bearing phosphonic acid groups, namely the poly(N-n-propylacrylamide-stat-2-(methacryloyloxy)methylphosphonic acid) (P(NnPAAm-stat-hMAPC1)) were synthesized, and their sorption properties for three divalent cations (Ni(2+), Ca(2+), Cd(2+)) and one trivalent cation (Al(3+)) have been investigated. The sorption experiments were performed with inc...

K. Janiszewski, Silesian University of Technology, Department of Metallurgy, Katowice, Poland. Hitherto existing investigations concerning the ceramic fi lter use in the steel making processes (both of laboratory and industrial scale) have given good results. The obtained results of fi ltration (in the laboratory) have proved that this method may be used as an eff ective and cheap way of steel ...

SUMMARY: In Europe almost 80 million tons of waste are annually combusted in Waste-to-Energy plants. Solid residues generated thereby contain altogether about 69,000 t/a of Zn, of which more than 50 % accumulates in air pollution control (APC) residues. Recent research activities aiming at Zn recovery from APC residues resulted in a large scale Zn recovery plant at a Swiss waste incinerator. By...

During the last two decades, extensive attention has been paid on the management of environmental pollution causal by hazardous materials such as heavy metals. Decontamination of heavy metals in the soil and water around industrial plants has been a challenge for a long time. A number of methods have been developed for the removal of heavy metals from liquid wastes such as precipitation, evapor...

In this article various pipes used for transporting of gas are introduced and pros and cons of each one are elucidated. The pipes are categorized in three different subgroups including metallic, polymeric and metallic-wire reinforced polymeric pipes. Metallic-wire reinforced polymeric pipes are nominated as the best option for usage in high pressure pipelines transporting natural gas. As a resu...

The aim of this study was to assess the potential of a human cell line containing the hsp70 promoter linked to the chloramphenicol acetyltransferase reporter gene in evaluating the toxic potential of complex mixtures. Cells were exposed to eluates of industrial wastes and the cellular responses were compared with the metal contents of the samples and with standardized aquatic (microalgal growth...

microwave energy has potential for the efficient heating of minerals. minerals or materials, which couple to microwave energy are called dielectrics and many valuable minerals are found to be dielectric. the mineral ilmenite is one which shows good dielectric heating characteristics. in this paper, the effect of microwave heat energy on the partial reduction of oxidized ilmenite oxidized in ...

During summer, melt ponds have a significant influence on Arctic sea-ice albedo. The melt pond fraction (MPF) also has the ability to forecast the Arctic sea-ice in a certain period. It is important to retrieve accurate melt pond fraction (MPF) from satellite data for Arctic research. This paper proposes a satellite MPF retrieval model based on the multi-layer neural network, named MPF-NN. Our ...
