Oxidation of d-glucose in the presence of 2,2′-bipyridine by CrVI in aqueous micellar media: a kinetic study

Biosorbents for hexavalent chromium elimination from industrial and municipal effluents

“…The electrostatic attraction between charged species and micellar head group is also important here and this depends on the pH of the solution. In addition, the proper choice of non-functional surfactant will speed up the relatively slow biosorption process [311][312][313][314][315]. The rate of biosorption can be increased by the proper choice of adsorbent; in this respect ascorbic acid containing biomaterial may be a good choice.…”

“…In this respect non-functional surfactants [311][312][313][314][315] may be useful. Non-functional surfactants will provide better insight into the reaction mechanism with preferential partitioning of the reactants in hydrophobic and hydrophilic layer.…”

Glucose promotes the reduction of hexavalent chromium in soil

“…Various factors could have concurred to the increased Cr(VI) reduction rate in the presence of glucose. Chemical reaction between chromate and glucose may have occurred into the soil solution and since, as also reported by Bayen et al (2005), chromate serves as a terminal electron acceptor. The mechanism of the reaction, also reported by Bayen et al (2005), is briefly summarised in Fig.…”

Kinetic study of oxidation of galactose by N-bromo phthalimide in the presence of cationic micelle in acidic medium

“…Energy is stored in the complex molecular structure of the carbohydrates [1][2][3][4]. The kinetics of oxidation of sugars has been the subject of extensive research in recent years [5][6][7][8][9][10]. The versatile nature of N-halogeno compounds is due to their ability to act as sources of halonium cations, hypohalite species, and nitrogen anions, which act as both bases and nucleophiles.…”
