a novel, simple, sensitive and effective method has been developed for preconcentration of lead. this solid-phase extraction adsorbent was synthesized by functionalization of graphenes with covalently linked n -methyl-glycine and 3, 4-dihydroxybenzaldehyde onto the surfaces of graphite. the method is based on selective chelation of pb (ii) on surfactant coated c 18 , modified with functionaliza...
A series of new di-, tri-, and tetranuclear Co(II) and Cu(II) complexes of three new diSchiff base ligands were synthesized by two different methods. The first method involved the synthesis of the three ligands from condensation reaction of 3,4-dihydroxybenzaldehyde (L'H2) with ethylenediamine (en), o-phenylenediamine (o-PD), or 4,5-dimethyl-1,2-phenylendiamine (DMPD) in a mole ratio of 2 : 1 f...
Over the past decade, there has been a great deal of interest in graphene with regards to its electrochemical behavior. Previous studies have focused on understanding fundamental processes such as charge transfer and molecular transport at the graphene-electrolyte interface as well as on applications of graphene in electronic, optical, and mechanical systems. We present illustrative examples of...
Catechols are a class of substances from natural or synthetic origin that contain a 1,2-dihydroxybenzene group. We have characterized the glucuronidation by rat liver microsomes and by the rat liver recombinant UDP-glucuronosyltransferase isoforms UGT1A6 and UGT2B1 of a series of 42 structurally diverse catechols, including neurotransmitters, polyphenols, drugs, and catechol estrogens. Small ca...
