Method & Evidence

AimTo investigate the efficacy of treated Teff straw as a low-cost adsorbent for removing various heavy metal ions from textile industry wastewater.

MethodExperimental investigation using batch adsorption techniques and isotherm modeling.

ProcedureTeff straw was treated to become an adsorbent. Batch experiments were conducted to study the adsorption of Cr, Cd, Pb, Ni, and Cu from simulated textile effluents. The influence of contact time, pH, temperature, and adsorbent dose was analyzed. Langmuir and Freundlich isotherm models were applied to characterize the adsorption process.

ContextTextile industry wastewater treatment, agricultural waste valorization.
