I am planning to synthesize AgNP using plant extract as a bioreductor.
I have come across several papers recommending a neutral to alkaline pH range (pH 7-8) to achieve silver nanoparticles with characteristics such as small size (
Michelle Darmawan
Use a green extract pH of 7-8. Adding alkali or acid may cause the extract components to decompose.
Thank you for the advice Sir Yuri Mirgorod . If I may ask, how can I prepare my plant extract to achieve a pH of 7-8 without adding acid or base?
You can try to achieve this pH by increasing the temperature, pressure, or adding another extract.
Thank you very much for the explanation and guidance, sir Yuri Mirgorod. I will try to implement it.
