salinization is the main characteristic of soils in arid and semi-arid regions which reduce the agricultural potential ofirrigated lands. therefore, soil reclamation as well as determination of the leaching requirement for salt control is veryimportant for better plant growth. in this study, the effects of leaching on saline soils of sistan region, southeast of iranwere examined using unsaturat...

Precious metal refining from ore or electronic devices includes hydrometallurgical processes with major concern about toxicity wastewater production. As an alternative, one-step electroleaching-electrochemical deposition process (EL-ECD) using ionic liquid mixtures was evaluated for palladium and gold recovery. A halide based combined a diluting chosen among ten electrolytes after cyclic voltam...

Municipal solid waste incineration bottom ash was treated with specially designed dry and wet treatment processes, obtaining high quality bottom ash granulate fractions (BGF) suitable for up to 100% replacement of natural gravel in concrete. The wet treatment (using only water for separating and washing) significantly lowers the leaching of e.g. chloride and sulfate, heavy metals (antimony, mol...

The stability and compatibility of topotecan hydrochloride with common infusion solutions and containers were studied. During this study, the leaching of diethylhexyl phthalate (DEHP), a major plasticizer of some polyvinyl chloride (PVC) materials was also investigated. A formulation of topotecan hydrochloride was added to 50 ml PVC infusion bags, polyolefin infusion bags and 150 ml glass bottl...

The influence of pH on the leaching behaviour of air pollution control (APC) residues produced in municipal solid waste incineration (MSWI) is addressed in this study. The residue is considered hazardous waste, and in accordance with their chemical properties, the leaching of contaminants into the environment is the main concern. Several leaching tests can be used for research studies or regula...

Abstract In this research, a recycling process for palladium using “dry aqua regia,” which consists of iron(III) chloride–potassium chloride, was proposed. Palladium dissolved in and the recovered by leaching with potassium chloride solution added ammonium nitric acid. almost completely 3 h at 600 K, recovery ratio up to 80%. addition, dissolution coexistence platinum platinum-palladium alloy r...
