Abstract:
Aquatic humic solutes were isolated in parallel by the non-ionic macroporous DAX-8 and diethylaminoethyl cellulose (DEAE-cellulose) resins from Nile river. Non-humic substances and humic substances which were separated from the water samples were determined. In addition, humic and fulvic acids were also determined. Quantitative measurement of aquatic humic substances was carried out by Total Organic Carbon Analyzer (TOC). Generally, concentrations of the Non-humic substances were greater than the humic substances in water samples. The fulvic acid concentration of the water samples examined ranged between 1.36 and 4.67 mg C L-l, while the level of humic acid ranged between 0.72 and 3.04 mg C L-l. DEAE-cellulose gives a useful conventional sorbing solid in the isolation of the bulk of aquatic humic substances over DAX-8.
