Synthesis of zn- al-3,4,5- trihydroxybenzoic acid – layered double hydroxide (ldh) by direct method and its controlled release activity / Siti Hafizah Aminuddin
Synthesis of new hybrid nanocomposite material zinc-aluminium-3,4,5-trihydroxybenzoic acid (Zn-Al-Gallic acid) was successfully attained by the direct method with a molar ratio of Zn to Al; R=4 at different concentration of 3,4,5-trihydroxybenzoic acid in the range between 0.05 M to 0.5 M. The synth...
