Uptake cadmium (cd2+) by znalco3 hydrotalcite / Azinyana Shawal
Hydrotalcite is also known as layered double hydroxides (LDH) has an ability as adsorbent to adsorb metals such as cadmium. Its potential is depends on their interlayer ion that can hold and remove the cadmium metals. In this study, the ZnAl-CO3-HT was chosen to remove cadmium and it was prepared by...
