Abstract

Researching on Methylene Blue dye treatment ability with Nano material (CoFe2O4 synthesized by co-precipitation method) combined with Bio gum (extracted from Osaka Seeds (Cassia Fistula Linn). Research results show that with Bio gum base material fully covered by magnetic nanoparticles of size 70-95nm (SEM) and the presence of several specific functional groups for bio gum and ferromagnetic oxide Nano (FT-IR). When adding OH group to Nano material, the adhesive ability to bio gum and the size of the particle does not change. Results of comparative studies on the application of Nano-Bio gum and Nano-OH-Bio gum materials showed that when studying the dyeing color of Methylene blue, the treatment efficiency is from 62.43 to 78.72%, decreasing from 349.67 Pt-Co. 74.41 Pt-Co at pH 6-7 and dosage at 1.5g/l. Based on the above results, Nano-Bio gum is able to treat dyeing color better than Nano OH-Bio gum. Therefore, Nano - Bio gum can become suitable material for the application of color treatment in practice.
