Typha latifolia leaves have been exploited as low cost biosorbent for remediation of
aqueous media contaminated with the reactive dye Drimarene Blue K2RL (DB-K2RL) discharged from
textile effluents. The effect of parameters such as initial concentration of dye, amount of bio-sorbent,
initial pH, shaking time and speed were investigated to evaluate its sorption capacity. The maximum
sorption was observed on adding 0.03 to 0.05 g mL–1
sorbent at pH 2 at 200 rpm for 2 hr shaking time.
The sorption efficiency of acid treated sorbent was also determined and its kinetic data was analyzed
using Freundlich and Langmuir models. The uptake capacity of both native sorbent and pretreated
biosorbent was compared and it was found that pretreated biosorbent exhibited better sorption ability
(qmax= 3.5 mg/g) as compared to the native biosorbent (qmax= 2.5mg/g).
