Evaluasi Kinerja Nanopartikel Perak (AgNP) Tertudung Glukosa dalam Pendeteksian Ion Fe3+ pada Rentang pH Lebar
Keywords:
ion Fe3 , AgNP, hipsokromik, absorbansiAbstract
Kandungan ion Fe3+ yang berlebih pada tubuh dapat memberikan dampak yang signifikan terhadap kualitas hidup masyarakat. Oleh karena itu, perlu dikembangkan metode deteksi ion Fe3+ yang cepat, sederhana dan murah. Salah satunya yaitu dengan memanfaatkan nanopartikel perak (AgNP) tertudung glukosa sebagai agen pendeteksi ion Fe3+. Pada penelitian ini mengkaji kemampuan AgNP dalam mendeteksi ion Fe3+ pada variasi pH 2 hingga 12. Hasil uji kinerja AgNP menunjukkan bahwa pH 2 merupakan pH optimum. Penurunan intesitas absorbansi lebih tinggi daripada pH lain yang ditandai dengan nilai D absorbansi paling besar. Hal ini juga ditandai dengan pergeseran ke panjang gelombang lebih rendah (hipsokromik) dari 412 nm menjadi 401 nm.
