In northern coastal industrial park, inlet of the wastewater treatment plant (WWTP) had characteristics low carbon source and high chloride ion concentration, which resulted in its poor biodegradability. this case, experiment explored an electrochemistral method to remove nitrogen. Cathodic potential, Ti/IrO2 was confirmed as anode − 1.6 V taken potential order nitrate-N. The findings include: ...

The corrosion inhibition performance of acetylacetonate complexes of zinc(II), manganese(II), cobalt(II) and copper(II) on the mild steel substrate in 1M H3PO4 was studied using DC polarization. It was seen that the mentioned complexes decreased corrosion rate of mild steel in phosphoric acid media due to the adsorption on metal surface. The potential of mild steel shifted toward more active po...

A series of TiAlON coatings were synthesized in a gaseous mixture of argon, nitrogen and oxygen by cathodic arc evaporation method using a Ti–Al mosaic target. Oxidation of coatings was carried out by heating the coated samples at the temperatures of 500, 600, 700, and 800°C for 1 h in air atmosphere. It was found that heat treatment changed the microstructure and composition of the coating. Th...

Rhodamine B (RhB) exhibits strong cathodic electrogenerated chemiluminescence (ECL) in aqueous solutions during high-amplitude p l l e w s ©

Cathodic hydroxylation of organoboron compounds was successfully performed under an oxygen atmosphere, producing the corresponding phenol derivatives with high selectivity and efficiency.
