The Application of Sawdust from Bamboo and Rain tree to Adsorb Cd(II) for Develop the Quality of Life in Community
This experiment study concern the removal of Cd(II) by using waste from wood in community such as sawdust
from Bamboo and Rain tree. The adsorption parameters were the initial amount of sawdust, the initial of various pH, the
initial concentration of heavy metal, the interference ion on the adsorption and application to water sample. The maximum
adsorption capacity on the adsorption of Cd(II) by using Atomic Adsorption Spectrophotometry was obtain by used sawdust
from Rain tree 0.25 g, pH = 3, initial metal concentration 200 ppm, and NaNO3 in solution, respectively. The adsorption
capacity of Cd(II) in water sample were 0.162 and 0.178 mol/kg by using sawdust from Bamboo and Rain tree, respectively.
This result confirmed that sawdust in community could remove the heavy metals from water in environment to enhance the
quality of life of people in community. Sawdust is effective and inexpensive materials to remove high amounts of heavy
metal from water.
