Fwd: Third Announcement

Dear colleague,

I would like to invite you to submit a paper to the MMC2008, which will be held at Universiti Kebangsaan Malaysia on 3- 4 December 2008 .

MMC 2008 is a national event on metallurgy and related field, and is a continuity of NMC 2007, NMC 2006 and 2004 Metallurgical Conference.

The purpose of this conference is/are to provide national platform for networking between metallurgical local scientists and researchers. To establish an avenue to present ideas and research studies and to share and discuss research findings and disseminate knowledge in the area of metallurgy.

Submitted papers will be published in conference proceeding and selected presented papers will be published in Sains Malaysiana or International Journal of Mechanical and Materials Engineering (cited by Scopus) after normal reviewing procedure. It is my great pleasure if you also can invite your college and postgraduate student to join the conference. In addition, the conference fee is very competitive for the field in the country.

Chemical composition of Fly ash by Inductively Coupled Plasma/Mass Spectroscopy (ICP/MS)

1. Powdered samples were scrapped from each of the four test materials. 100 mg of each powdered sample was weighed and poured into a Teflon screw capped jar (SavillexR).
2. 2 ml concentrated nitric acid (HNO3) was added to each jar and the jars tightly capped.
3. The jars were placed on a hot plate at a temperature of 150°C until the entire samples were dissolved.
4. The solutions were then transferred into separate 125 ml bottles, their jars rinsed thoroughly with water and transferred into appropriate bottles.
5. About 15 ml of water was then added to fill each bottle. The solutions were analyzed using Perkin Elmer Elan 5000 inductively coupled plasma/mass spectrometer (ICP/MS).

6. Using the protocol of internal standardization, about 30 parts per billion (ppb) In, Tb and Bi were added into each sample solution so as to overcome instrumental drift and matrix effect.
7. The high thermal energy and electron rich environment of the ICP resulted in the conversion of most atoms into ions.
8. A quadruple mass spectrometer permitted the detection of ions and each mass in rapid sequence, allowing signals of individual isotopes of an element to be scanned.

Chemical composition of Fly ash by Inductively Coupled Plasma/Optical Emission Spectroscopy (ICP/OES)

1. The fly ash sample was totally digested by gently heating 0.25g of the sample in a mixture of HF/HNO3/HClO4 in a Teflon beaker on a hot plate until dry.
2. The residue was then dissolved in 5% HNO3 and topped to 15 ml with deionized water for analysis by Perkin Elmer Optima 3000 DV inductively coupled plasma/optical emission spectrometer (ICP/OES).
3. This was used to determine the major element oxides, with the exception of SiO2, and the larger suite of trace elements. 0.10 g of fly ash sample was also digested with 2.25 ml of a mixture of 9 parts HNO3 with 1 part HCl for 1 hour at 95°C in a boiling water bath and topped to 15 ml with deionized water for analysis by the ICP/OES.
4. This method was used to determine the smaller suite of trace elements.
5. The SiO2 portion was obtained by fusing 0.10 g of the fly ash sample with 1.00 g of lithium metaborate at 1000°C for 1 hour.
6. The residue was dissolved in dilute HNO3 topped to 100 ml with deionized water and then analyzed by the ICP/OES.
