In order to explore the effects of bagasse on the absorption of dye waste water
simulated wastewater of methylene blue used as the main pollution composition
it investigated the absorption effects of the bagasse on the methylene blue in aqueous solution under different conditions
such as different bagasse dosage
pH
shaking time
initial concentration of methylene blue and temperature.The results indicate that the absorption rate of methylene blue is up to 95% in solution with initial methylene blue concentration of 100 mg/L
bagasse dosage of 3 g/100 mL
pH of 6~7
shaking time of 15 minutes and temperature of 30 ℃. The theoretical saturated absorption amount of bagasse is 12.71 mg/g at 30 ℃. Langmuir

Temkin models and secondary absorption rate equation can be used to suitably describe the absorption process of bagasse to methylene blue in aqueous solution
and the main absorption pattern is physical absorption.
