Unformatted text preview: nthesis of sorghum. Young developing anthers of fertil e and male sterile lines of Sorghum (104 A and 104 B lines), were used for biochemical analysis. Biochemical analysis of RNA, total proteins and carbohydrates of gene -cytoplasmic male sterile sorghum lines has been investigated in detail with respect to differences in male sterile and fertile lines. Thus our results clearly indicate that, in sorghum reproductive failure and fertility restoration are gametophytic, occurring during macromolecular syntheses and mitosis stages of pollen development. The microsp ores of fertile anthers show synthesis of macromolecules like RNA and proteins and pollen mitosis leading to the formation of vegetative and generative nuclei. The microspores of sterile pollen do not show any signs of synthesis of RNA and proteins, nor undergo mitotic (pollen mitosis) division. 237 23rd-25th June 2010 3rd ICYC 2010 Universiti Sains Malaysia OTH-P3 SYNTHESIS AND CHARACTERISATION OF AMINO-PHOSPHORYLATED MULTI-WALLED CARBON NANOTUBES (Am,p-MWCNTs) FOR THE REMOVAL OF LEAD FROM AQUEOUS SOLUTIONS L.M. Muzingu, *X.Y. Mbianda and L.M. Cele Department of chemical technology, University of Johannesburg, Doorfontein Campus, P.O. Box 17011, Johannesburg, South Africa E-mail: firstname.lastname@example.org Carbon nanotubes (CNTs) are hollow nanosize tubes consisting of graphene sheets capped with pentagons and hexagons at each end. A particular interest is attached to the study of carbon nanotubes because of their physical, chemical, mechanical, electrical properties. Several studies have being carried out in water treatment using carbon nanotubes. Both unfunctionalized and functionalized carbon nanotubes have been reported as effective adsorbents for metal trace in aqueous media. We wish to report in this paper the synthesis and characterisation of amino -phosphorylated multi-walled carbon nanotubes (Am,p-MWCNTs) and their uses in the removal of lead in aqueous solution. MWCNTs were synthesized by nebulized spray pyrolysis method and treated with a mixture of sulphuric and nitric acid to yield...
