. banana peel in a glass tub. After a predetermined time interval the mixture was centrifuged and ltered and quantity of dye not adsorbed, i.e. that remaining in solution, was measured by spectrophotometer. ltration. In Figure 3 the dye removal percentage by different masses of adsorbent is shown. The results indicated that increase in mass of adsorbent to 0.4 g leads to increasing in BB...
