SEQUESTERING ATTRIBUTES OF TYPHA LATIFOLIA AS A LOW COST BIOSORBENTFOR THE REMOVAL OF REACTIVE DYE (DB-K2RL) FROM AQUEOUS MEDIA

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