Electrochemical study of simple coumarin and its determination in aqueous infusion of Mikania glomerata

The authors considered the reduction of the volume of the dried material and, consequently, the reduction of its area available for heat and mass transfer, and showed that the ratio

This study reports on a development of a simple and fast method for the simultaneous determination of Cd and Pb in antibiotics by GFAAS using a tungsten coating on

In solutions of pH higher than 8.5 the reduction peak was not observed (data not shown), which indicates that the product of oxidation of H 3 CAF became unstable and an

The main purposes of this work were to investigate vanadium(V) oxide as a catalyst in the pyrohydrolysis of coal for fluoride determination using ISE, and the construction of a

We observed from a simple theoretical model that the reduction of RSA signal due to the presence of peripheral groups is caused by the reduction of the ratio between excited and

The voltammetric peaks obtained at –0.78 V, –1.35 V, and –1.70 V for amfepramone in acidic and alkaline medium are characterized by irreversible reduction processes, which have

This work presents the validation results of a simple, fast and low-cost sample preparation method for the determination of pesticide residues in soil by ultrafast

This work presents a simple, fast and low-cost methodology for the simultaneous determination of paracetamol (PC) and ibuprofen (IB) in pharmaceutical formulations by
