ADSORPSI LIMBAH METHYLENE BLUE TERHADAP LIMBAH BIOMASSA NANASAdsorpsi Limbah Methylene Blue terhadap Limbah Biomassa Nanas

Dyes such as batik dyes and the textile industry can pollute enviroment, especially receiving water bodies. The use of pineapple biomass waste an adsorbent for removal (methylene blue). Adsorption experiment using were varied in dose, contact time stirring speed. In this study, used consisted pure activated biomass. experimental result showed that masses into 0,5,1,2,5,3, dan 3,5 gr 250 mg/L glass, mass does not affect color removal. Where highest efficiency was 68%. (AA) adsorbed more methylene blue than unactivated (AM). While at trial 5 variations with a span 30,60,90,120 150 rpm, it found higher speed heigher increase experiment, 72% 90 rpm. isotherm suitable adsorption is langmuir which allows to occur physically or chemically limited monolayer layer. high ability after being reduse by average 70% terms period, strring
