AB  - The purpose of this research investigated the adsorption ability and determined the appropriate condition for adsorption of lead (Pb<SUP>2+</SUP>) in synthetic wastewater by <I>Luffa cylindrical</I> Fiber (LCF) and 0.5 NaOH Modified <I>Luffa cylindrical</I> Fiber (MLCF). All the experiments were carried out in the batch experiment. Adsorption parameters consisted of NaOH concentration, pH, contact time, temperature, adsorbent size, agitation speed, adsorbent does and initial Pb<SUP>2+</SUP> concentration. Moreover, the adsorption isotherm and desorption ability were examined for understanding the adsorption mechanism. The results indicated that the suitable condition for adsorption of lead (Pb<SUP>2+</SUP>) by LCF and MLCF was pH 4.0, contact time 30 min, temperature 40&deg;C, adsorbent size 250-600 &#956;m, agitation speed 250 rpm, adsorbent dose 10 g L<SUP>-1</SUP> and initial Pb<SUP>2+</SUP> concentration 25 mg L<SUP>-1</SUP>. In this condition, the adsorption ability of LCF and MLCF were 82.72 and 94.93%. The adsorption data was fitted well by Langmuir isotherm. The results can conclude that LCF and MLCF is an efficient adsorbent for Pb<SUP>2+</SUP> contamination adsorption in wastewater. Finally, the LCF and MLCF utilization is an alternative waste management or environmental conservation.
