The estimation of water quality parameters such as the concentration of TSS (Total suspended sediments) and Chl-a (Chlorophyll-a) from satellite images is strongly depend on the accuracy of atmospheric correction and water quality parameter retrievals algorithms (Ruddick, Ovidio, and Rijkeboer 2000; Chlorophyll extraction by three solvents in three aquatic plants Total chlorophylls of duckweed extracted by 80% acetone, 90% acetone, and 95% ethanol were 0.648 * 0.012 mg g-', 0.860 * 0.008 mg g-', and 0.745 * 0.018 mg g-', respectively. Abstract: The goal of this study was to model the total leaf chlorophyll content (LCCtot) of Gannan navel orange leaves using a field imaging spectroscopy system in the visible and near-infrared domain. 663) 3. Total Chlorophyll (mg) in original tissue sample = Total Chlorophyll (mg/mL) x final volume (mL). The "chlorophyll ¿z" values given by the equation of Talling & Driver (1963) for acetone extracts were approximately equal to the values for total chlorophyll a + phaeophytin a given by the equation of Lorenzen (1967). Because of differences between the absorption spectra of pure chlorophylls a and b in DMSO and 80% acetone, formulae to calculate the individual concentrations of chlorophyll a, chlorophyll b and total (a + b) chlorophyll in pigment extracts were redetermined for specific use with DMSO.
