Uniform silver nano particles can be obtained through the reduction of silver ions by ethanol at a temperature of
80°C to 100°C under atmospheric conditions . In this synthesis process, 20 ml of aqueous solution containing silver nitrate (0.5g of AgNO3), 1.5 g sodium linoleate (C18H32ONa), 8 ml ethanol and 2 ml linoleic acid (C18H32O2) are added in a capped tube under agitation. The system is sealed and treated at the temperatures between 80°C to100°C for 6 hours.

2. sodium linoleate à 15 g
3. Ethanol à 50 mL
4. linoleic acid à 50 mL
