Zinc Oxide Nanoparticles Green Synthesis – ZnO by using Zinc Sulphate as precursor and Aloe Vera Leaves as reducing and stabilising agent via Biological Method.

CHECK LIST

Fresh leaves of Aloe Vera Leaves, Zinc Sulphate, Deionized Water, RB Flask, Dropper, Magnetic Stirrer with Temperature option, Filter Paper

STEP 1.

Take fresh leaves of Aloe Vera. Wash properly and cut them into small pieces.
STEP 2.

Take 20g leaves pieces in 100ml of deionized water and boil the leaves around 60ºC for 10 minutes.
STEP 3.

When the water turns GREEN, filter it out and use it as reducing and capping agent for Nanoparticles synthesis.
STEP 4.

Take 6g Zinc Sulphate in 150ml deionized water; and set the temperature 60ºC.
STEP 5.

Add 20ml leaf extract (prepared in step 3) into Zinc Sulphate solution and stir it for 3 hours at 60ºC.
STEP 6.

Centrifuge the off-White color opaque solution at 5000 rpm for 10 minutes and dry it to obtain powder of Zinc Oxide Nanoparticles.
RESULTS

UV-Vis absorbance peak shown at 360nm. Average size of spherical Zinc Nanoparticles was found to be around 15-20 nanometers.
NOTE: All the experiments should be done under the guidance of lab Incharge; and proper lab safety instructions.
