Phosphogypsum, a by-product of the phosphate industry (80%% pure) and reagent grade calcium chloride were applied to soil columns.
Analytical grade nickel chloride hexahydrate (NiCl2 · 6H2O) and hydrazine hydrate (N2H4 · 6H2O) were purchased from Sinopharm Chemical Reagent Co., Ltd., Shanghai, China.
Analytical grade sodium chloride (NaCl, 100.1% pure), sodium nitrate (NaNO3, 99.7% pure), and potassium nitrate (KNO3, 99.5% pure) were used to synthesize dissolved and dry salt mixtures.
Analytical grade sodium chloride (NaCl) and sodium sulphate Na2SO4 are used to produce solution with known amounts of salts and electrode rinse solution, respectively.
Phosphogypsum (PG) and reagent grade calcium chloride were applied to packed sandy loam soil columns and leached with canal water (SAR = 4, and EC = 2.16 dS m−1).
The synthetic saline groundwater utilized in the extraction experiments was prepared from ultrapure water and 25 g/L analytic grade sodium chloride (NaCl), which corresponds to the salinity of the Hettangian aquifer.
CaCl2·6H2O was prepared using industrial grade calcium chloride (CaCl2), and then 10, 15, 20 and 25 wt% MgCl2·6H2O was added into CaCl2·6H2O respectively in order to obtain CaCl2·6H2O MgCl2·6H2O eutectic hydrate salt PCM.
The Dead Sea is a major source for the production of food grade Sodium Chloride (NaCl) through the use of traditional salt grinding, multiple washing stages and then evaporation.
Adsorption kinetic study was carried out by dissolving analytical grade sodium chloride in distilled water to prepare sodium stock solution containing 500 mg/L, then adding different sodium concentrations to fixed adsorbent dose at constant temperature in shaking water bath at (25 °C ± 02).
Medical grade poly vinyl chloride) (PVC) sheets and tubes were surface modified by nucleophilic substitution of chlorine atoms of PVC by photoactive N,N-diethyl dithiocarbamate (DTC) in aqueous media in the presence of a suitable phase transfer catalyst (PTC) at 55°C.
