Heavy metals are considered hazardous to health if they accumulate excessively in the human body. The adsorption process using adsorbents can remove iron metal ions. In this study, removal of heavy metals such as ferrous metal (Fe) was done by adsorption with nanosilica. Nanosilica is made from rice husk ash contains 80-90% silica so that it can be utilized as a raw material in nanosilica synthesis. Synthesis of nanosilica carried out using a KOH solution with varied concentration (1.5; 2.5; 3; 3.5 and 4 M). The five types of nanosilica applied to textile waste containing ferrous metal (Fe) in five different duration ((5, 10, 15, 20 and 25 minutes). Textile waste containing iron metal that was analyzed by AAS to see the remaining iron content. From the analysis of AAS produced the smallest iron concentration of 0.186 ppm in nanosilica with 1.5 M KOH solvent. Nanosilica with 1.5 M KOH solvent was characterized using a SEM-EDX tool to obtain a surface morphological size of 0.44 μm with 28.95% SiO2 content.
