Abstract:
Poly (acrylamide-acrylic Acid)/multi-walled carbon nanotubes composite [P(AAm-AA)/MWCNTs] was prepared by gamma radiation to initiate the copolymerization of AAm and AA onto MWCNTs surface. The structural characteristics were confirmed by FT-IR, SEM, XRD, TGA and DTA. The particle size distribution was determined by dynamic light scattering (DLS). [P(AAm-AA)/MWCNTs] was used to study the adsorption efficiency of 47Sc from natural calcium by batch technique at different concentrations of HCl and/or HNO3 acid solutions. No-carrier-added 47Sc (III) was separated from 47Ca(II) on [P(AAm-AA)/MWCNTs] column matrix. The elution efficiency of about 80 ± 1.5% was attained for 47Sc(III) using 1M HNO3. Three quality control tests, radionuclidic, radiochemical and chemical purities were investigated to emphasis that 47Sc secure for use in nuclear medicine.

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
