Graphite as a potential adsorbent for ammonium ions removal / Haszalina Abdul Halim, Nur Alwani Ali Bashah and Norhusna Mohamad Nor

The main focus of this work is to evaluate the potential of graphite powder as an adsorbent for ammonium ions (NH4+ ions) removal. Surface functional groups and thermal analysis of graphite adsorbent were conducted by using FTIR and TGA analyses, respectively. The experimental work covered batch ads...
