Methylene blue (MB) is a dye in wastewater from textile industries that pollutes the water environment.Reduction of its content is necessary for protecting humans and the surrounding environment.This study fabricated chitosan/Fe3O4 nanocomposite through the mixture of chitosan from crab shell waste and magnetite (Fe3O4) from local sand iron with sodium tripolyphosphate (STPP)-sulfate crosslinker as an adsorbent to reduce methylene blue content.The obtained composite was characterized by Fourier Transform Infrared (FTIR) Spectrophotometer and X-Ray Diffraction (XRD) instrument.The contents of Nakiri Knives methylene blue before and after applying Fridge Water Hose Tap Connector adsorbent-based nanocomposite were determined using an ultraviolet-visible (UV-Vis) spectrophotometer.

FTIR characterization results show that chitosan and chitosan/Fe3O4 nanocomposite had successfully synthesized based on the typical vibrational peaks.The deacetylation degree of chitosan was 69.79%.Fe3O4, and chitosan/Fe3O4 nanocomposite, were confirmed by XRD patterns.The chitosan/Fe3O4 nanocomposite adsorption capacity reached 45.

37 mg/g when adsorption occurred with 20 mg adsorbent, pH 9, and contact time of 1.5 h.Hence, the chitosan/Fe3O4 nanocomposite in this study has potency and is applicable to adsorb MB effectively.
