Abstract

Research has been carried out regarding the use of biopolymers in the form of strach as a modification of Fe2O3 which is used to reduce the concentration of dyes in industrial wastewater. Fe2O3 (NF) nanoparticles and their modification with Strach (NF-Strach) were synthesized using bottom-up methods and co-precipitation techniques. NF and NF-Strach were successfully used as adsorbents to reduce liquid waste contaminated with dyes. The adsorption test showed that NF-S was able to adsorb better than NF in 10 ppm methylene blue dye, the resulting adsorption efficiency reached 98%. The regeneration test showed that both NF and NF-Strach could be reused even though the adsorption capacity decreased as the number of repeated contacts increased. The adsorption test on liquid waste from the textile industry resulted in a decreased adsorption efficiency when compared with contact with 10 ppm methylene blue.
