Submitted: Jun 17, 2013; Accepted: Jul 29, 2013; Published: Aug 07, 2013 Abstract: The study was conducted to identify the potential used of organic acid modified activated carbon (AC-RCOONa) to remove ammonia from an aqueous solution using a batch and fixed-bed column adsorption. The optimum conditions for adsorption in the batch study occurred at pH range(More)
Addition of waste material as Supplementary Cementitious Material (SCM) in blended cement has been proved to have a positive effect to cement matrix. It also as an alternative method to reduce the environmental problem regarding the waste management and Ordinary Portland Cement (OPC) production. This paper presents the effect of particle size of Waste Paper(More)
Three new triorganotin dithiocarbamate complexes of the type [(C H ) Sn(S CNR(C H )] (R = CH , 6 5 3 2 6 11 3 C H and i-C H ) have been successfully synthesized. These compounds were characterized by elemental 2 5 3 7 analysis, FT-IR and NMR( C) spectroscopy. A single crystal X-ray analysis of the triphenyltin(IV) N13 cyclohexyl-N-isopropyldithiocarbamate,(More)
Benzene, a known human carcinogen and likely poses significant health effects, is a major air pollutant emitted from anthropogenic activities. This study aims to investigate the performance of ZnO nanoparticles (nZnO) coated on 13X zeolie combination with ozone and UV system to treat benzene contaminated air stream. The adsorbents were characterized by SEM(More)
New adducts of dithiocarbamate compounds have been successfully synthesized by the reaction of bis(N-sec-butyl-N-propyldithiocarbamato)cadmium(II) with 2,2’-bipyridyl or 1,10-phenanthroline. Elemental and gravimetric analysis showed that the molecular formula of these adducts were Cd[S CN(s-C H )(C H )](L) 2 4 9 3 7 (L = C H N or C H N ). These adducts were(More)
There are various cause of river pollution in Malaysia, one of them are sourced from dumping site. A study on water quality at Sungai Batu that located adjacent to the dumping site was being conducted where it was capped for more than 10 years ago and has been developed as housing estate namely Taman Wahyu II, that located in Selayang, Selangor. This study(More)
