Separation Using Foaming Techniques
Separation of various chemical components from each otheJO is often the most difficult step in analytical procedures. The problems attached to separation become further magnified when the species concentations are extremely low. A group of techniques that has proven useful especially in dilute solutions for separating and concentrating metallic as well as nonmetallic ions and complexes, protein...
متن کاملPlant protection with inorganic ions.
Gradients of salts of the specific ion repellents for Meloidogyne incognita -- NH, K, Cl, and NO -- have been demonstrated to shield tomato roots from infestation in soil. The strategy of these greenhouse experiments was to interpose a salt barrier in a soil column between the plant roots and the nematodes. The relative effectiveness of the salts as a barrier to infective second-stage juveniles...
متن کاملDevelopments in sample preparation and separation techniques for the determination of inorganic ions by ion chromatography and capillary electrophoresis.
A review is presented of sample preparation and separation techniques for the determination of inorganic ions by ion chromatography (IC) and capillary electrophoresis (CE). Emphasis has been placed on those sample treatment methods which are specific to inorganic analysis, and the developments in separation methods which are discussed are those which enhance the capabilities of IC and CE to han...
متن کاملElectrochemical behaviour of lead in hydrochloric acid solution in the presence of inorganic ions
The electrochemical behaviour of lead electrode in hydrochloride solution containing variousoxo-anions at different concentrations was studied by using of cyclic voltammetry (CV) method.Results obtained show that the addition of these inorganic compounds decreases the anodic andcathodic currents peaks according to the following order: H2PO4- > HPO42-> SO42-. It’s revealedalso that the cathodic ...
متن کاملNovel inorganic membranes for gas separation
A literature survey was performed to evaluate the state-of-the-art membrane systems for CO2/CH4 separation which is critical in the natural gas industry. The systems that were reviewed included zeolite, carbon, polymeric, mixed matrix, amorphous silica, and supported ionic liquid membranes. Supported ionic liquid CO2/CH4 selective membranes were synthesized in our laboratory by applying room te...
