Removal effeciency of blue basic dye41 by using Fe3O4 magnetic nanomaterial.

Abstract

The study was conducted in January 2023. The study used nano-iron oxide treatment, iron oxide coated with citric acid, and nano-iron oxide grafted with wheat hulls, in the adsorption of basic blue dye 41 from the medium. Three criteria are used: knowing the best time to remove the dye, the best medium that helps in the adsorption method, and the best concentration of the dye that can be removed the fastest. The results were as follows: The best time: Fe3O4 was (10.50) minutes with a 97% removal rate, NM-AC was 10 minutes with a 94% removal rate, NM-BO was 10 minutes with a 98% removal rate. The best pH for Fe3O4 was at pH 6 with a removal rate of 97%. NM-AC was at pH 6 with a removal rate of 92%. NM-BO was at pH 6 with a removal rate of 97%. The best concentration of Fe3O4 is 10 ppm with a 98% removal rate, NM-AC is 10 ppm with a 98% removal rate, n NM-BO is 30 ppm with a 98% removal rate. A spectrophotometer device was used. We conclude. From the study, the chemical precipitation method was used to produce nanosized iron oxide, nanosized iron oxide coated with citric acid, and nanosized iron oxide grafted with wheat hulls, and the surfaces prepared in this study were used as adsorbent surfaces. Research recommendations: Synthesis of nanoparticles in a green chemical method based on cheap and locally available materials.
