Abstract

Zn(OH)2 nanopartikel telah disintesis melalui metode elektrokimia. Logam seng (Zn) digunakan sebagai anoda dan katoda. Pengaruh potensial, konsentrasi dan waktu elektrolisis pada pembentukan Zn(OH)2 nanopartikel diamati. Produk nanopartikel dikarakterisasi dengan XRD, Zeta Sizer, TEM dan spektrofotometer UV-Vis. Difraktogram menunjukkan bahwa nanopartikel yang diperoleh sesuai dengan pola difraksi standar dari Zn(OH)2, nanopartikel yang dihasilkan memiliki struktur orthorhombic. Nilai Absorbansi tertinggi dari analisa UV-Vis diperoleh pada λ = 229 nm dengan potensial 20 V dalam natrium sitrat 0,04 M selama 20 menit. Nilai absorbansi tertinggi mengindikasikan bahwa Zn(OH)2 nanopartikel terbentuk paling banyak pada kondisi tersebut. Karakterisasi menggunakan Zeta Sizer menunjukkan bahwa Zn(OH)2 nanopartikel memiliki distribusi ukuran dari 37 sampai 255 nm dengan volume tertinggi 96,296 nm. Zn(OH)2 nanopartikel yang diperoleh dari metode ini memiliki bentuk spherical (bulat). =========================================================================================== Zn(OH)2 nanoparticles have been synthesized using electrochemical method. Zinc metals were used as anode and cathode. The effects of potential, concentration and time of the electrolysis on the formation of Zn(OH)2 nanoparticles were observed. Nanoparticles product was characterized using XRD, PSA, TEM and UV-Vis spectrophotometer. The diffractogram shows that the nanoparticles obtained is in a good agreement with standard diffraction pattern of Zn(OH)2, identified as orthorhombic structure. Highest absorbance value of UV-Vis analysis was obtained at about λ = 229 nm with potential applied 20 V in 0.04 M sodium citrate for 20 minutes. Highest absorbance value indicate Zn(OH)2 nanoparticles formed the most in this conditon. The characterization using Zeta Sizer shows that the Zn(OH)2 nanoparticles have a size distribution from 37 to 255 nm with the highest volume at 96.296 nm. Zn(OH)2 nanoparticles have spherical form were obtained by this method.
