A rapid and simple sequential potentiometric method is described for the determination of nitrate and chloride ions in vegetables, by using home-made ion selective electr odes. The extraction of both ions from the vegetabl e samples was effected by magnetic stirring of the samples during 30 min in water at room temperature. Direct Potent iometry was used as analytical technique for measurement. The mean coefficient of variation, the average percentage of spi ke recovery and the detection limit…

A NEW, FAST AND SENSITIVE POLAROGRAPHIC METHOD FOR THE DETERMINATION OF TRACE AMOUNTS OF NITRATE AND APPLICATION TO RAW POTATOES
Nitrate in food stuff can be reduced to nitrite and may form nitrosamines which are known as carcinogenic substances. Thus, its concentration has to be controlled by highly sensitive methods. In this
A Simple Electrochemical Method for Nitrate Determination in Leafy Vegetables
A fast and easy electrochemical method for nitrate determination in leafy vegetables was developed. It is a much cheaper method compared to the HPLC method or chemiluminescence detection, the most
Studies on the Selective Hybrid Organic Inorganic Composite Materials
Poly-o-toluidine zirconium(IV) ethylenediamine (PTZE) was synthesized to explore its behaviour towards nitrate sorption. The material was characterized by FTIR, XRD, TGA, DTA, SEM and TEM. The
