dc.description.abstractEnvironmental pollution by heavy metals becomes a serious problem with the increasing use of heavy metals in the industrial field. One of the widely used methods for removing heavy metals from liquid waste is adsorption using magnetic nanoparticles. Samples of beach sand that have been processed with an Iron Sand Separator (ISS) and separated by NdFeB (Neodymium Iron Boron), crushed by ball milling for 60 hours using a ball size variation of 0,5; 0,7; and 1,5 cm. The product is called ball milling product phase I (PBMT I).PBMT I is separated again by using NdFeB magnets, then in ball milling phase II with a time variation of 20, 40, and 60 hours (PBMT II). The crystal size and magnetic phase of magnetic nanoparticles are determined by the X-Ray Diffraction (XRD) method and heavy metal adsorption is determined using AAS (Atomic Absorption Spectroscopy).. XRD results show that magnetic nanoparticles have 2 magnetic phases namely magnetite (Fe3O4) with cubic crystal structure and hematite (α − Fe2O3) with monoclinic crystal structure. AAS results showed that Cu ion adsorption increased with increasing milling time, whereas the percentage value of adsorption in a row is 27,2%, 40,5%, and 64,7%, while for Pb adsorption ions decreased with increasing milling time of 46,1%, 35,6%, and 11,8%, respectively.en_US
