CHARACTERISTIC PHYSICOCHEMICAL OF BAMBOO-BASED ACTIVATED CARBON FOR COAL RUN-OFF WATER TREATMENT USED AT PT.BUKIT ASAM SLUDGE SETTLEMENT POND

The aim of this research were investigated bamboo-based activated charcoal (ABT)characteristics using Scanning Electron Microscopy (SEM) and Fourier Transform Infrared (FTIR). ABT has been successfully synthesized through physico-chemical activation at 700°C with H3PO4 10% solution as activator. resulted porous surface structure bamboo causes an absorption interaction pollutants (cations, anions, suspended solids/TSS) in wastewater. Bamboo different physical characteristics from other types raw materials because the lignin composition is wood. spectral patterns AB are similar but differ intensity. functional groups detected two same, there differences intensity where relatively lower, especially hydroxyl around 3400 1600 cm-1. This decrease due to dehydration process that occurs during both chemical processes so come out
