Boron (B) adsorption on two arid-zone soils from the San Joaquin Valley of California was investigated as a function of equilibrium solution B concentration (0–250 mg L), solution pH (3–12), and electrical conductivity (EC, 0.3 or 7.8 dS m). Boron adsorption on both soils increased with increasing pH, reached a maximum near pH 9, and decreased with further increases in pH. Boron adsorption as a...

Biopolymers are viewed as effective and eco-friendly agents in soil modification. This study focuses on the wettability analysis of polyacrylamide (PAM) solutions for soil remediation. The contact angle, surface tension, and viscosity of PAM solutions were experimentally evaluated in air- and decane-biopolymer solution systems. Furthermore, a micromodel was used to investigate the pore-scale di...

The aim of this research is to get a better understanding of the electrolytic refining process in order to yield the anode slime. Three types of secondary copper anodes are electro refined in an electrolytic system, where the electrolyte is an acid of copper sulphate solution. As a result of the electro-refining process the anode slime has been gained as secondary product. The experimental ...

BACKGROUND It has been suggested that oxygen (O2) diffusion could be favored in water enriched in O2 by a new electrolytic process because of O2 trapping in water superstructures (clathrates), which could reduce the local pressure/content relationships for O2 and facilitate O2 diffusion along PO2 gradients. MATERIALS AND METHODS Mitochondrial respiration was compared in situ in saponin-skinne...

phytoremediation is an emerging environmental-friendly technology that can be a promising solution to remediate oil-polluted soils. the impact of high amount of hydrocarbons on growth characteristics of burningbushand common flax was evaluated in this survey. the influence of organic fertilizers was also assessed on growth of plant species in oil-contaminated soil. soil samples in which plants ...

" Scire est nescire, nisi id me Scire alius sciret." october, 1923. A large body of evidence has accumulated in support of the electrolytic dissociation theory originally put forward by Arrhenius in 1887, and at the present time the conception of the reaction of a solution, whether acid, alkaline or neutral, is to be regarded either from the point of view of the absolute quantity of neutralisab...
