An Investigation of Inorganic Background Soil Constituents With a Focus on Arsenic Species
… kinds of soils, its bioavailability and speciation. Arsenic soil sorption analyses were conducted in the laboratory on clay loam, light clay, sand and silt loam soils. These experiments demonstrated that the sorption of arsenic was dependent on soil type and time of soil exposure to the …

Fabrication, Validation, and Performance Evaluation of a New Sampling System for the In-Situ Chemical Speciation of Chromium Ions in Groundwater Using Supported Liquid Membranes (SLMs)
… has been fabricated to facilitate the in-situ speciation of Cr. Teflon® was selected as the material for the samplers because of its inert chemical nature. The design of the sampler is based on the Supported Liquid Membrane (SLM) extraction technique, which utilizes charged organic carrier …
