The adsorption properties of treated PAL samples toward MB were investigated. The experimental conditions were 0.025 g of grinded PAL sample mixed with 50 mL of 500 mg/L MB solution (pH=7.0) in 100 mL flask, and shaken on a thermostatic shaker (THZ¨C98) with a constant speed of 120 rpm at 30 ¡ãC for 660 min to reach the adsorption equilibrium. The residual concentration of MB solution after adsorption was measured with a Specord 200 UV/visible spectrophotometer (Germany) by monitoring the absorbance at a wavelength of maximum absorbance (670 nm). |
