Study on Application of Biocomposite Bio-Material Prepared from Ferromagnetic Nano Oxide and Biogum Extracted from Cassia Fistula Seeds in Methylene Blue Treatment

摘要

Researching on Methyllen Blue dye treatment ability with Nano material (CoFe₂O₄ synthesized by co-precipitation method) combined with Biogum extracted from Osaka Seeds (Cassia Fistula Linn). Research results show that with Biogum base material fully covered by magnetic nanoparticles of size 7095 nm (SEM) and the presence of several specific functional groups for biogum and ferromagnetic oxide nano (FT-IR). When adding OH group to nano material, the adhesive ability to biogum and the size of the particle does not change. When adding the OH-grouping to the nanomaterials, it was shown that nanoparticles of unmodified size and high porosity were adhered to the Biogum substrate forming a closely linked block (SEM image). Research results show that the optimum pH (Nano - Biogum and NanoOH - Biogum at pH = 7) and optimal dosage (Nano - Biogum and NanoOH - Biogum using 1.5 g/L), the adsorption capacity of Methylene Blue dye of Nano - Biogum (78.72%) gave better adsorption efficiency than Nano OH - Biogum (62.43%). With the results of research shows that Nano - Biogum material can extend the application of materials to absorb color into practice.
