Absorban Ion Logam Cu (Ii) Berbasis Hidrogel Superabsorban CMC - G - Pka/Naalg Dengan Teknik Iradiasi Sinar Gamma

Abstract: Hidrogel Superabsorban (HSA) CMC-g-PKA/NaAlg telah disintesis menggunakan iradiasi sinar gamma sebagai crosslinker dengan dosis 10 kGy. HSA disintesis dengan variasi massa CMC, yaitu 1,0 g, 1,5 g, 2,0 g, dan 2,5 g. Kemampuan HSA dalam menyerap ion logam Cu (II) telah dipelajari menggunakan spektrofotometer UV-Vis. Pengujian dilakukan dengan variasi konsentrasi ion logam Cu (II) yaitu, 1%, 2%, 3%, 4%, dan 5% selama 30 menit. Nilai absorbansi pada ion logam Cu (II) meningkat seiring dengan peningkatan massa CMC.… Show more
