aluminium pans that are placed in the sample and reference compartments. The primary function of the metal pan is to contain the test specimen and to enable intimate contact with the furnace. Previously it has been demonstrated that a DSC can be linked to a
hotspot in the future.
In the preparation of carbon nanofiber web by electrospinning, the degree of pre-oxidation determined the structure and performance of carbon nanofiber to a large extent. The pre-oxidation process of PAN fiber is more

polymer matrix can be achieved simply by blending and compressing the solid mixture. Recently, Lu and Pan [ 12 ] realized a fine dispersion of nano-SiO x particles in PPS simply by pulverizing of the mixture through a ball-milling technique. However, for
Four composite materials with di-(2-ethylhexyl) phosphoric acid (HDEHP) as an extraction agent and PAN as a binding polymer
were studied in this work. The intended use of these materials is in extraction chromatography. They were prepared by various
methods and contained different amounts of HDEHP. The properties were compared by studying europium uptake from nitric acid
solutions. Materials prepared by direct incorporation of extraction agent into PAN polymer during beads production and with
up to 40% (w/w) of HDEHP are suitable for analytical separations. Materials with high capacity can be prepared by impregnation
of ready-made PAN beads.
Conditions are established for the substoichiometric determination of iridium employing 1-/2-pyridylyzo/-2-naphthol /PAN/ as a chelating agent. Iridium forms a red coloured complex /12/ with PAN at pH 5 /acetate buffer/, on heating for 60 min in a boiling water bath. The complex was extracted with chloform. Tens of micrograms of iridium were determined with an accuracy of ±0.38%. Effects of diverse metal ions on the determination of iridium were studied and methods for suppression of interferences were developed.
