  • Substitute of sodium hydrosulfite in bleaching of talc ore ...

    Hello,Sodium hydrosulfite (or sodium dithionite) is an excellent reducing agent. It acts as a hematite reductant in bleaching process of talc; the reaction is very fast at room temperature. The problem is that the talc becomes contaminated with sulfur compounds. Can anyone suggest another bleachin

    To rule out the possibility that dithionite inactivated pri-miRNA processing, we added dithionite to pri-miRNA processing assays reconstituted using NC9, a DGCR8 construct that does not contain heme due to the lack of the HBD but is active in pri-miR-30a (pri-miRNA of miR-30a) processing (Fig. 1A).

  • Bleaching of wood pulp - Wikipedia

    Bleaching of wood pulp is the chemical processing of wood pulp to lighten its color and whiten the pulp. The primary product of wood pulp is paper, for which whiteness (similar to, but distinct from brightness) is an important characteristic. These processes and chemistry are also applicable to the bleaching of non-wood pulps, such as those made from bamboo or kenaf
