<![CDATA[Telah dilakukan penelitian tentang kinetika fotodegradasi remazol yellow dengan menggunakan ZnO dan ZnO yang disisipi 1%, 3%, 5%, 7%, dan 9% Ag yang disintesis dengan metode kopresipitasi. Eksperimen kinetika dilakukan melalui penentuan konsentrasi remazol yellow yang tersisa setelah interaksi ZnO dan ZnO-Ag dengan larutan remazol yellow yang disinari UV selama 0, 20, 40, 60, 80, 100, 120 dan 140 menit. Selanjutnya data dianalisis mengikuti model kinetika reaksi orde pertama. Hasil penelitian menunjukkan bahwa laju reaksi fotodegradasi oleh ZnO meningkat dengan penambahan konsentrasi dopan AgA research on photodegradation kinetics of remazol yellow using ZnO and Ag-doped ZnO (1, 3, 5, 7 and 9 wt% Ag) synthesized by co-precipitation method had been studied. Kinetics experiment was performed by determining the concentration of remazol yellow remained after interaction of ZnO and ZnO-Ag with remazol yellow solution that were irradiated by UV-light at 0, 20, 40, 60, 80, 100, 120 and 140 minutes. Data obtained was analyzed using firs-order kinetics model. The results showed that photodegradation rate was increased with the increasing Ag concentration.]]>
