Potentiometric Sensor for Furosemide Determination in Pharmaceuticals, Urine, Blood Serum and Bovine Milk
A construção, avaliação e aplicação analítica de um sensor potenciométrico do tipo PtHgHg 2 (Fur) 2 Grafite, onde Fur significa íon 4-cloro-N-furfuril-5-sulfamoil-antranilato, são descritas. O eletrodo responde a Fur com sensibilidade de (−58,4 ± 0,9) mV década no intervalo de 5,0 × 10-1,0 × 10 mol L, a pH 7,0-9,0 e com um limite de detecção de 3,8 × 10 mol L. O eletrodo é facilmente constru...
متن کاملA New Potentiometric Sensor for Determination and Screening Phenylalanine in Blood Serum Based on Molecularly Imprinted Polymer
Methods routinely utilized for detection of phenylalanine in new-born blood consist of enzymatic assays, lacking sensitivity and HPLC assays which are expensive and time-consuming to conduct. We, here, report for the first time, the construction of a phenylalanine sensitive electrode, on the basis of a selective molecularly imprinted polymer, offering sensitivity, economy and ease of use for th...
متن کاملOfloxacin determination in urine, serum and pharmaceuticals using an automatic flow potentiometric system.
An automatic system was developed to determine ofloxacin in biological fluids and pharmaceutical formulations. Drug detection was carried out by a potentiometric membrane sensor based on [bis(trifluoromethyl)phenyl]borate as molecular-recognition material. The tubular shaped detector system was solidly attached to the manifold, creating a high-throughput stable setup (50 samples per hour) appro...

متن کاملDevelopment of novel potentiometric sensors for determination of lidocaine hydrochloride in pharmaceutical preparations, serum and urine samples
This article is focused on the determination of lidocaine hydrochloride as a local anaesthetic drug. A potentiometric method based on modified screen-printed and modified carbon paste ion-selective electrodes was described for the determination of lidocaine hydrochloride in different pharmaceutical preparations. It was based on potentiometric titration of lidocaine hydrochloride using modified ...
