The aim of this work is synthesis of AgNPs from cold and hot extracts of Eucalyptus leaves.After that, microwave irradiation has used to improve properties of these nanoparticles read more which applied to degrade methylene blue (MB) dye.The change in color of the mixture was from yellow to ruby-brown and to dark brown for the synthesized AgNPs from the cold extract (CAgNPs) and the hot extract (H-AgNPs) of Eucalyptus leaves respectively.

The biosynthesized H-AgNPs showed the highest absorbance at the beak of 440 nm compared as 430 nm for C-AgNPs.HM-AgNPs exhibited the smallest average of diameter reached 57.94 nm and the best degradation reached 71.

34% compared with H-AgNPs (39.27%) after 24 h.The improved HMAgNP using microwave irradiation was efficient in facilitating the degradation processes of the Azo-dye.

This paper will lead to candidate suitable, cheap, eco-friendly and greener AgNPs for rapid degradation of damaging merrick backcountry wet cat food textile dyes.
