Rapid titrimetric estimation of arsenic in biological material

Titrimetric Biosensing of Biological Wastewater Treatment Plants

The development of titrimetric sensor applications to monitor biological wastewater treatment processes is shortly described, and the measurement principle (based on a pH controller) is illustrated. 3 applications that were developed during the past years are used to illustrate the capabilities of titrimetric sensors. The ammonium and the nitrate concentration can be measured to monitor the nit...

Determination of Arsenic in Biological Material by Hydride Generation Atomic Absorption Spectrometry Method

A hydride generation atomic absorption spectrometry method for arsenic determination in biological material was prepared. The samples were digested in muffle furnace at 550oC. The ash was dissolved in 4.5 N hydrochloric acid and the final solution was diluted in 10% hydrochloric acid. The arsenic was determined using a Perkin-Elmer atomic absorption spectrometer equipped with electrodeless disc...

Rapid and Validated Hplc Assay for the Determination of Oxytetracycline in Biological Material

A rapid, accurate, simple, and reproducible high performance liquid chromatographic (HPLC) method for the determination of oxytetracycline hydrochloride (OTC) in porcine plasma has been developed and validated. The drug and the standard were eluted from 5 μm Omni Spher (Varian) C18 column (250 mm × 4.6 mm I.D.) at room temperature. The mobile phase was composed of ACN-MeOH-(HCOO)2 (17.5:17.5:65...
