OPTIMIZATION OF BIOSORPTION OF SAFFRANIN DYE BY USING PINEAPPLE (ANANAS COMOSUS) PEEL WASTE

Vaishnavi Ransing* and Dr. Sukhada Akole

ABSTRACT

Biosorption may be simply defined as the removal of substances from solution by biological material. Substances can be organic and inorganic, and in gaseous, soluble or insoluble forms. Biosorption processes are particularly suitable for effluent treatment containing low dye concentrations. Towards attaining a sustainable engineered chemical processes, pineapple peel waste (Ananas comoscus), a low cost agricultural waste material was investigated to serve as an adsorbent for removal of saffranin dye from wastewater. The process was carried out as a batch process. The main aim of this study was to investigate the adsorption of Saffranin onto pineapple peel. The effects of operating conditions such as initial dye concentration, contact time, pH effect, and temperature on adsorption of saffranin were studied. The optimum conditions for the same using pineapple peels were found to be as follows: pH 8, agitation 80 rpm, time 60 minutes, biomass concentration 100mg/L and dye concentration 25mg/L.
