Fig. 5From: Removing Disperse red 60 and Reactive blue 19 dyes removal by using Alcea rosea root mucilage as a natural coagulantEffect of slow-mixing speed on removal efficiency of Disperse red 60 and Reactive blue 19 dyes. (Initial pH = 11, Alcea rosea concentration = 200 mg/L and initial dye concentration = 40 mg/L for Disperse experiments; initial pH = 11, concentration = 250 mg/L and initial dye concentration = 20 mg/L for Reactive experiments)Back to article page
