Abstract

Research on the potential of nano montmorillonite as an adsorbent for Remazol Brilliant Blue dye waste has been carried out. Nano montmorillonite was isolated from Bener Meriah bentonite, Aceh, to be used as an adsorbent. The optimum conditions for adsorption of Remazol Brilliant Blue dye using nano montmorillonite occurred at a contact time of 60 minutes, pH 4, and adsorbent mass of 2 grams. The results showed that the adsorption of Remazol Brilliant Blue dye by nano montmorillonite followed the Freundlich isotherm model with R2 = 0.9858. The results of the regeneration test show that the montmorillonite nano adsorbent can be used repeatedly

Abstract

A research of preparation biodegradable plastics, from LDPE and cassava starch mixture with the addition of acrylic acid, had been conducted. This research purpose to  studied compatibility properties of the material and percent weight loss during the biodegradation test. Optimum weight loss (59,26% ) was showed after 60 days witches LDPE and starch composition ratio 6 : 4 (w/w)  while tensile strength  equal to 0,38 Kgf/mm2.  SEM characterization showed that biodegradation has occurred by  formation of hole in the biodegradable plastic surface. DTA test gave Tg = 130 °C, Tm = 230 °C and Td = 370-450 °C while FT-IR analysis showed that the biodegradable plastics have a chemistry interaction.
