A simplified method for the determination of dissolved organic carbon is based upon the ampoule–persulfate wet digestion procedure. The modification proposed involves use of a continuous stream of sparging gas (technical grade oxygen) during the ampoule sealing process to minimize entry of combustion products from the sealing flame. The method provides reliable results with a minimum of training and equipment compared with other methods of sealing ampoules. Further, the proposed method is inexpensive, relatively simple, and compares favorably with costly, automated analysis of dissolved organic carbon.

Concentration Levels

The purpose of the current study is to analyze the concentration levels of selected trace metals: Ca, Cu, Fe, K and Zn in medicinal plant Moringa stenopetala grown in SNNPR, Ethiopia. A wet digestion procedure is used. Thus, the result showed that the concentrations of Ca, Cu, Fe, K and Zn in Moringa stenopetala grown in Gamo Gofa (Arbaminch) were;2.80±0.36, 0.866±0.134, 7.98±1.23, 3.02±0.63 and 84±0.92 mg/Kg, in Wolaita 3.28±0.28, 0.94±0.16, 7.13±1.32, 7.13±1.32 and 0.61±0.11mg/Kg and in Konso were; 2.97±0.67, 0.77±0.098, 6.79±0.73, 2.39±0.23 and 0.37±0.006mg/Kg respectively.
