“…A column method has been used where nitrate adsorption was determined by the recovery of a known concentration of nitrate leached through the column, and desorption of adsorbed nitrate by water leaching (Kinjo et al 1971; Wong et al 1990a,b). In a differential extraction method, Herbel and Spalding (1993) Bufo et al (1990) detected two fractions of nitrate that were extracted by an electro-ultrafiltration method. They considered the more easily extracted fraction to be "soluble" and the other to be "reserye" nitrate.…”

A simple method is described for the determination of the ionic content of vegetable samples by ion chromatography with suppressed conductivity detection. Extracts of leaves of cucumber (Cucumis sativus), leaves and cotyledons of watermelon (Citrullus lanantus), cotyledons of zucchini (Cucurbitapepo), and leaves and roots of olive (Olea europaea) obtained at room temperature yielded chromatographic profiles with substantial differences in the relative contents of Cl-, NO3-, HPO4(2-) and SO4(2-) as well as of Na+, NH4+, K+, Mg2+ and Ca2+. Although NO3-, Cl- and K+ were common to each extracted sample and accounted for most of the ions present, two additional anion peaks (i.e. malate and oxalate) were detected. Among the vegetable tissues investigated, olive roots contained a considerable amount of oxalate (37 mg/g dry weight), while Na+, which is present in very low amount in extracted samples of leaves and cotyledons, represented ca. 30% of the cationic content of olive roots. In all the examined tissue extracts, K+ was the main cation (16-55 mg/g dry weight) and NO3-, Cl- and HPO4(2-) were the main inorganic anions.
