OPTIMASI EFISIENSI NANOPARTIKEL PERAK HASIL SINTESIS MENGGUNAKAN NATRIUM SITRAT DALAM MENURUNKAN KONSENTRASI METHYLENE BLUE

Abstract

Methylene blue is an organic dye that is widely used in various industries such as textile, paints, plastic and pharmaceuticals. Methylene blue is very stable so it is very difficult to degrade in nature and harmful to the environment. The aim of this research was to optimize pH of the solution and silver nanoparticles dosage in methylene blue removal. The synthesis of silver nanoparticles was carried out by adding sodium citrate as a reducing and stabilizing agent. The pH optimization was carried out with variations of pH 1, 2, 3 dan 4. The silver nanoparticles dosage optimization was carried out with variation of dosage 2, 4, 6 and 8 mg. The results showed that pH 2 and 6 mg silver nanoparticles were chosen as the optimum parameter. The silver nanoparticles synthesized by sodium sitrate was effectively remove the methylene blue 61,42%.
