| Summary: | The high content of lead in the wastewater become one of the major problem to the
industry because it will contaminate the environment and the ecosystem. The ability
of durian leaves treated with sodium hydroxide to remove Pb(II) ion was
investigated in this study. The CTDL was characterized by using pHslurry, pHzpc and
FTIR. The parameters of this study are pH, adsorbent dosage, and contact time. The
absorbance of each parameter was analysed using Atomic Adsorption Spectrometer
(AAS). The studies was conducted at pH 4, 0.04 g of CTDL, temperature of 30°C
for 90 minutes with 120 rpm. Kinetic data were analyzed by using two adsorption
kinetic model which are pseudo-first-order and pseudo-second-order. The data
shows high correlation coefficient on pseudo-second-order compared to pseudo-first-
order with R2 value is in between 0.997 to 0.999. The results of this study
suggest that durian leaves has potential as a low cost and effective adsorbent to
remove Pb(II) ion from waste water. |
