This research aims to synthesis AgNPs from waste frying palm oil (wfpo) using pH as
the parameter to control the size of AgNPs. It is synthesized by using pH 6, pH 8 and
pH 10. NaOH was used as the catalyst for the reaction while HCl was added to adjust
the pH condition. The color that shows the presence of Silver Nanoparticles is light
yellow to dark brown. Analysis of UV-Vis shows the presence of AgNPs at peak 415-
420 nm. AgNPs also have been characterize by using FTIR, XRD and SEM to shows
the structure and morphology of AgNPs. The synthesized AgNPs have shown good
performance in catalytic degradation of Methyl Orange that degraded within 10
minutes time interval. It act as the catalyst for degradation with the presence of
NaBH4. AgNPs shows smallest size in higher pH condition while largest size in least pH
value.
