Introduction: The therapeutic monitoring of lithium, through concentration measurements, is important for individual dose adjustment, as a marker of treatment adherence and to prevent poisoning and side effects. Objectives: Validate and compare two methods – atomic emission and atomic absorption – for the determination of lithium in serum samples. Methodology: Parameters such as specificity, pr...

This study concerns the oxidation of n-hexane. It was conducted in continuous flow fused-silica jet-stirred reactor (JSR) at 10 atm and an equivalence ratio 0.5. n-Hexane initial concentrations were (i) 2500 ppm with a mean residence time 1.5 s (ii) 1000 0.7 s; we operated cool-flame regime for temperatures ranging from 540 to 720 K 530 800 K, respectively. Products analyzed quantified gas phas...

a novel and selective method for the fast determination of trace amounts of zn(ii)ions in water samples has been developed.  the first additional carbonyl and carboxyl functionalized-nano graphene (spfnano graphene). the presence of additional carbonyl and carboxyl groups located at the edge of the sheets makes go sheets strongly hydrophilic, allowing them to readily swell and disperse in water...

A modeling study of benzene and phenyl radical formation was performed for three low-pressure premixed laminar flat flames having an unsaturated C2 or C3 hydrocarbon fuel (acetylene, ethylene, and propene). Predictions using three published detailed elementary-step chemical kinetics mechanisms were tested against molecular beam mass spectrometry (MBMS) species profile data for all three flames....
