Kinetic and thermodynamic studies on adsorption of copper ions onto pomelo peel (citrus grandis)
(Trans Tech Publications, 2013)
The ability of pomelo peel (PP) as natural adsorbent to remove Cu (II) ions from aqueous solution was investigated. The influence of solution pH, contact time and temperature were evaluated. Cu (II) removal increased as ...
A study of liberation and separation process of metals from printed circuit boards (PCBS) scraps
(Trans Tech Publications, 2013-12)
Since the metallic elements are covered with or encapsulated by various plastic or ceramic materials on printed circuit boards (PCBs), a pre-treatment process allowing their liberation and separation is first needed in ...
Alkali activated blast-furnace slag cement: The opportunity to solve sustainable issues
(American-Eurasian Network for Scientific Information, 2013)
This paper aimed at investigating the possibility of alkali activated blast-furnace
slag (BFS) to produce cement powder that could be alternative to ordinary Portland
cement. It was found that an alkali activated BFS ...
A study of comminution-liberation and floatability of Copper from printed circuit boards (PCBs) scrap
(Universiti Kebangsaan Malaysia (UKM), 2008-12-03)
Printed circuit boards (PCBs) were collected from obsolete or defective computers that are the largest source of the kind of waste. PCBs are composed of different materials such as polymers, ceramics and metals. The studies ...
