Abstract
Section titled āAbstractāBoron-doped diamond( BDD) film electrodes were deposited on Si substrates by direct current plasma chemical vapor deposition( DC-PCVD) system with CH4,H2 and B( OCH3)3as source gas. Salicylic acid( SA)was used as a trap of hydroxyl radicals to investigate the rule and mechanism of hydroxyl radicals produced by electrolysis with BDD electrode. It was found that the hydroxylated product of SA reaction with Ā·OH was 2,5-dihydroxybenzoic acid( 2,5-DHBA),instead of 2,3-dihydroxybenzoic acid( 2,3-DHBA). The optimum test condition for Ā· OH detection in BDD electrode system was 7 mmol / L SA initial concentration with 30 min reaction time under 10 m A / cm2 current density. The production rate of Ā· OH was 5. 789( mol /( L Ā· min)at 10 m A / cm2.
