Turbidity Effect on the Fluorescence Determination of Chlorophyll-a in Water

The effect of turbidity on the determination of chlorophyll a by laboratory fluorometry-RF5301-Spectrofluorophotometer and online fluorescence instrumentthe On-line Detector for Seawater' chlorophyll were investigated.Using the RF5301-Spectrofluorophotometer determined the fluorescence intensity value of chlorophyll a with different turbidity,using the On-line Detector for Seawater' chlorophyll determined the chlorophyll a concentration with the different turbidity Microcystis aeruginosa samples and water samples.Analyzed the turbidity effect on fluorimetric determination results of chlorophyll a.Researches showed that when the water turbidity was large, due to the strong scattering effect of suspended particulate matter the chlorophyll a determined by fluorometry were on the high side.
