TI  - Uptake of cationic dyes from aqueous solution by biosorption onto granular 
      kohlrabi peel.
PG  - 1319-23
AB  - A new, low cost, locally available biomaterial was tested for its ability to 
      remove cationic dyes from aqueous solution. Granules prepared from kohlrabi peel 
      had been utilized as a sorbent for uptake of three cationic dyes, methylene blue 
      (MB), neutral red (NR) and acridine orange (AO). The effects of various 
      experimental parameters (e.g., dye concentration, particle size, initial pH, 
      contact time and other factors) were investigated and optimal experimental 
      conditions were ascertained. Above the value of initial pH 4, three dyes studied 
      could be removed effectively. The isothermal data fitted the Langmuir model in 
      the case of NR sorption and the Freundlich model for all three dyes sorption. The 
      biosorption processes followed the pseudo-first-order rate kinetics. The results 
      in this study indicated that kohlrabi peel was an attractive candidate for 
      removing cationic dyes from the dye wastewater.
