Amira, Masitha Dwi (2017) Studi Pembuatan dan Karakterisasi Elektroda Perak pada Substrat Kaca menggunakan Metode Pengendapan. Sarjana thesis, Universitas Brawijaya.
Abstract
Elektroda perak pada substrat kaca preparat telah dibuat. Penelitian ini mempelajari pengaruh konsentrasi AgNO3 dan metode pengendapan terhadap sifat fisik dan kimia elektroda perak yang dihasilkan. Elektroda perak dibuat dengan metode pengendapan cermin perak, dimana glukosa sebagai gula pereduksi dicampur dengan larutan Tollens sehingga perak mengendap pada kaca preparat. Hasil sintesis dikarakterisasi dengan mikroskop optik dan dilakukan pengukuran hambatan menggunakan multimeter. Kekuatan mekanik elektroda perak di uji menggunakan alat sonikator selama tiga menit, dan dilakukan uji korosi menggunakan asam basa selama enam jam. Elektroda perak berubah warna menjadi kekuningan setelah dilakukan uji asam basa. Hasil sintesis menunjukkan konsentrasi optimum pada elektroda perak adalah 0,08 M dan metode pengendapan yang paling baik pada temperatur 60oC selama dua jam.
English Abstract
The silver electrodes on the glass substrate have been made. This research studied the effect of AgNO3 concentration and the precipitation method on the physical and chemical properties of the resulting silver electrode. The silver electrode is prepared by a silver mirror precipitation method, wherein glucose as reducing sugar is mixed with Tollens solution so that silver precipitate on the glass. The synthesis results is characterized by optical microscope and measurement of barrier using multimeter. The mechanical strength of the silver nanoparticle electrode was tested using a sonicator for 3 minutes, and a corrosion test using acid-base for six hours. The silver nanoparticles electrode changes color to yellowish after an acid-base test. The synthesis results showed that the optimum concentration of silver nanoparticles electrode is 0.08 M and the best precipitation method at 60° C for two hours
