N2  - In this study, has been carried out producing of mangrove wood activated carbon as
adsorbent through physical activation and chemical activation. Mangrove wood
activated carbon adsorbents obtained used to adsorption purple textile dye code 4.
The physical activation process finished at 500

0C for 1 hour and chemical activation
was perfomed using H3PO4 10% activator for 24 hour. Characterization of
mangrove wood activated carbon was carried out by using Scanning Electron
Microscopy-Energy Dispersive X-Ray (SEM-EDX) to determine the surface
morphology activated carbon. The adsorption test of mangrove wood activated
carbon to purple textile dye code 4 aim to find out optimum conditions of activated
carbon among others namely adsorbent weight, pH, contact time, concentration and
determine adsorption isotherm model. Adsorption of purple textile dye code 4 by
mangrove wood activated carbon occurs at optimum conditions with an adsorbent
weight of 0,08 grams at pH 3 with contact time for 120 minutes and solution
concentration 100 ppm. The adsorption isotherm of purple textile dye code 4 tend to
follow the Freundlich adsorption isotherm model with correlation coefficient value
(R2
) was 0,9607.
