Ciprofloxacin is an antibiotic that belongs to the class of drugs known as quinolones and it is frequently used to treat a variety of bacterial infections. The present work aims the development of a simple, cost‐effective, and environmentally friendly method for the determination of ciprofloxacin in drugs and artificial urine samples due to the high importance of this antibiotic for the human health...
A novel platform for electrocatalysis of isoniazid (INH) based on 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) and reduced graphene oxide (rGO) immobilized in a Nafion® membrane was developed. The composite (DDQ/rGO) was characterized by Fourier-transform infrared spectroscopy (FTIR) and the sensor response for the analyte was studied by cyclic voltammetry (CV) and chronoamperometry techniques. The...
A flow system for the simultaneous determination of ammonium and phosphate in river water at the μg ml -1 level employing a low expensive LED-based photometer is described. The manifold of the flow system comprised four analytical pathways containg a set of three-way solenoid valves and an automatic injector commutator. The signal measurements of both analytes were carried out using two...
