Effect of Polyvinyl Alcohol (PVA) on Gold Nanoparticles Synthesized using Teak Leaf Extract (Tectona grandis)

Muhammad Yasser

Abstract


Telah berhasil disintesis nanopartikel emas dengan menggunakan ekstrak daun jati (Tectona grandis) dan ligan Polivinil Alkohol (PVA). Terbentuknya Nanopartikel emas ditandai dengan terbentuknya warna merah anggur dan serapan pada panjang gelombang maksimum berkisar 500 nm – 600 nm. Pertumbuhan dan kestabilan nanopartikel emas yang dihasilkan diamati dengan menggunakan Spektroskopi UV-Vis. Hasil pengamatan selama 144 jam menggunakan Spektroskopi UV-Vis, yang diperoleh kestabilan nanopartikel emas yang pada waktu 120 jam yang ditandai dengan serapan panjang gelombang maksimum pada kisaran 568 nm– 568,5 nm.
