The importance of subsoil features for phosphorus (P) leaching is frequently mentioned, but subsoil effects are still poorly documented. This study examined whether the subsoil of four agricultural Swedish soils (two sand and two clay) functioned as a source or sink for P leaching by measuring P leaching from intact soil columns with topsoil (1.05 m deep) and without topsoil (0.77 m deep) over ...

Landfills generate emissions over long periods, often longer than a lifetime. The longest lasting emission is leachate. In order to estimate the future requirements for leachate treatment, different kinds of leaching tests may be applied. In this paper, shaking leaching tests (SLT), landfill-simulator leaching tests and a field-cell leaching test performed with ash, municipal solid waste (MSW) ...

There are more than 150 ports in China and a considerable proportion of dredged sediments waterways contaminated with heavy metals as the typical contaminants. It is mandatory to remediate prior further resource utilization. The over-arching objective this study was use natural organic acids (oxalic acid, citric tartaric malic acid) leaching agents remove (Cu, Cd, Pb) from sediments. Batch expe...

BACKGROUND, AIMS, AND SCOPE Heavy metal contaminants in environment, especially in drinking water, are always of great concern due to their health impact. Due to the use of heavy metals as catalysts during plastic syntheses, particularly antimony, human exposure to metal release from plastic bottles has been a serious concern in recent years. The aim and scope of this study were to assess metal...

Abstract Magnesium chloride hexahydrate crystal (MgCl 2 .6H O) is an intermediate product used to obtain Mg metal from its ores. This work aims produce purified MgCl O crystals natural Egyptian serpentine. Serpentine samples were collected the Eastern Desert in Egypt and prepared for leaching with HCl solutions. Reaction temperature (°C), time (h), solid/liquid ratio (g/mL), acid concentration ...
