Optimisasi Adsorpsi Ion Pb(II) Menggunakan Zeolit Alam Termodifikasi Ditizon
(2012)
Lead (Pb) is one of heavy metals pollutants in the environment. Adsorption appears to be the most widely used for removal of the heavy metals. The aim of this research is to improve the performance of zeolite by modification ...
Preparation of Zeolite A from Coal Fly Ash as Adsorbent for Ni(II) and Zn(II)Preparasi Zeolit A dari Abu Layang Batu Bara sebagai Adsorben Ni(II) dan Zn(II)
(IPB ( Bogor Agricultural University ), 2012)
Fly ash is waste of coal that can be converted into zeolite. Zeolite A was synthesized from fly ash by fusion of NaOH:fly ash, namely 0.8:1, 1:1, 1.2:1, and 1.4:1 at fusion temperature and reaction time of 450, 550, and ...
