Pembuatan Dan Karakterisasi Nanopartikel Perak Menggunakan Ekstrak Kulit Buah Naga Merah Sebagai Pendegradasi Metilen Biru
This search has been done manufacture and characterization of silver
nanoparticles using red dragon skin extract as a methylene blue degradation. This
research was aims to synthesize nanoparticles using red dragon fruit peel extract
characterized using a UV-Vis spectrophotometer and characterization using TEM
and determining the degradation activity of methylene blue which was tested
absorption using a UV-Vis spectrophotometer. Silver nanoparticles with various
volume of red dragon fruit peel extract and silver solution namely 1:3,1:5 and 1:7.
Synthesis of silver nanoparticles in red dragon fruit peel extract using a UV-Vis
spectrophotometer which is produced an absorbance of 0,5962 a.u, 0,6321 a.u and
0,9878 a.u at a wavelength of 416 nm, 432 nm and 433 nm. Characterization
using TEM was to produce a particle size of 20,02- 40,09 nm with a particle
structure of FCC. The degradation activity of methylene blue for the absorption
test using UV-Vis spectrophotometer at a concentration of 25 ppm, 50 ppm dan
75 ppm in an optimal time of 8 hours resulted in degradation efficiency values of
99,64%, 99,17% and 99,27%.
