| Summary: | Durian leaf powder was chemically modified by introducing sulfur groups with the
carbon disulfide treatment in alkaline medium. The presence of sulfur groups on durian
leaf Xanthate were identified by FTIR spectroscopic study. Batch adsorption study was
applied to investigate the effect contact time, initial coencemtration of Pb(II), adsorbent
dosage and pH on Pb adsorption. The studies were conducted at pH 4, XDL dosahe is
0.05g, in contact time of 90 minutes and temperature of 30°C. kinetics data were
analyzed using two adsorption kinetics model which is pseudo-first-order and preudosecond-
order with R2 between 0.9987 to 0.9995 rather than pseudo-second-order model |
