| Summary: | The textile industry is one of the producers of waste water. The use of biomaterial as adsorbents can be an <br />
<br />
<br />
alternative environmentally-friendly technology for the processing of waste water. Seaweed have the ability <br />
<br />
<br />
to adsorb metals and polar organic compounds because it contains polysaccharides, lipids or proteins on <br />
<br />
<br />
the surface of the walls of the cell. Those compounds can act as a binding site because it containing hydroxyl <br />
<br />
<br />
functional groups, such as amino, hydroxyl, and carboxyl. This research used the powder seaweed <br />
<br />
<br />
Sargassum sp. soaked with HCl 0,1 M as a methylene blue dye adsorbent. Optimization of adsorption <br />
<br />
<br />
includes parameters of pH, contact time, the mass of the adsorbent and initial concentration of methylene <br />
<br />
<br />
blue. This research results that pH optimum adsorption conditions in pH 3, masses of adsorbent 0,1 gram, <br />
<br />
<br />
adsorption time of 60 minutes, and this adsorben can adsorp methylene blue up to of 1000 mg L-1. <br />
<br />
<br />
Adsorption process follow the Langmuir isotherm with the maximum adsorption capacity of 294.12 mg g- <br />
<br />
<br />
1 at 25˚C. Kinetic studies suggest that methylene blue adsorption kinetic model follows the pseudo second <br />
<br />
<br />
order. Desorpsi as much as 3 cycles have been done using HCl 0,1 M solution. |
