In the present study, a magnetic fucoidan composite was prepared and characterized with infrared Fourier transform (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM) techmices. The effect of magnetic fucoidan composite in the adsorption of methylene blue was investigated. Based on the obtained results, the maximum adsorption capacity of magnetic fucoidan was 104.16 mg / g. In addition, magnetic fucoidan-copper (I) composite was prepared and identified by the mentioned techniques. Also Cu (I) loading was observed with X-ray energy scattering (EDX) technique. The performance of the nanocatalyst obtained in synthesis of 1, 2, 3-triazoles in water and ethanol was eva‎luated, and the products obtained from this reaction were also identified by nuclear magnetic resonance and IR spectroscopy. The advantages of this catalyst include easy separation from the reaction medium, recyclability, biocompatibility, non-toxicity and cost-effective preparation.
