Produção de carvão ativado utilizando semente de tamarindo

Abstract

The food and pharmaceutical industries use tamarind as a source of raw material for the production of pasta, juices and medicines. During production, the seeds are discarded and only one pulp is used, generating waste. The search for methods for reappropriation of data stocks is being developed, such as an activated carbon production. Thus, this work was developed with the purpose of producing a low cost adsorbent material using the precursor as tamarind seeds to bind the medium, sodium hydroxide (3:1 m / m). The right to demonstrate, therefore, the importance of presenting their qualities (6,5951 ± 0,2294%), low ashes (1,9883 ± 0,0156%) and high volatile support content (97,9690 ± 0.0155%). The adsorbent material was analyzed by means of Fourier transform (FT-IR) radiation analysis, pH without zero charge point (6,87), iodine number (989,645 ± 22,782 mg g-1) methylene (286.1972 ± 3.9885 mg g-1). The results indicate that the adsorbent material increased has the microporous characteristic. Chemical activation was efficient because the initial levels of NI and AMI for in natura were increased after activation, which may also justify the efficiency and values of these factors are greater than the results for the commercial trade.
