Trace Analysis of Niflumic Acid in Milk and Human Plasma by Ion-pair-based Vortex Assisted Dispersive Liquid-liquid Microextraction Combined with UV-Vis Spectrophotometry
A simple, accurate and fast vortex-assisted dispersive liquid-liquid microextraction procedure has been developed for the extractive spectrophotometric determination of niflumic acid in biological samples. The method is based on the formation of an ion association complex between niflumic acid and methylene blue. The resulting ion-pair was extracted into dichloromethane and its absorbance was m...

متن کاملDevelopment of a Simple and Efficient Method for Preconcentration and Determination of Trace Levels of Fexofenadine in Plasma and Urine Samples
A simple, inexpensive and sensitive three-phase hollow fiber liquid-phase microextraction (HFLPME) coupled with high performance liquid chromatography (HPLC) with UV detection was successfully developed for determination of trace level of an anti-Histamine drug, fexofenadine, in human plasma and urine. The analyte was extracted into n-octanol that was immobilized in the wall of a porous hollow ...
متن کاملInfluence of human urine combined with farm yard manure and chemical fertilizers on french bean and maize cropping sequence in lateritic soils of Karnataka, India
The introduction of ecological sanitation (ECOSAN) toilets in villages near Bangalore hascreated opportunities for safer sanitation and recycling of human excreta, as fertilizers, in ruraland peri-urban areas. Field experiments were conducted at the University farm on French beansand Maize as the test crops in succession for 2 consecutive years in the same field. Differenttreatment combinations...
