In order to improve adsorbing performance and stability of chitosan in acid simultaneously, cross-linking was employed after the protection of amino groups for improving its stability, then the protection of amino groups was removed and protonated to obtain high adsorption performance. With formaldehyde as amino-group protective agent and glutaraldehyde as(More)
Four amino cobalt phthalocyanine is a promising photosensitizer, so the study of its spectrum is of great significance. The density functional B3LYP/3-21G* method was used in optimizing the structure of the four configurations of four amino cobalt phthalocyanine, which can calculate the energy of its most stable structure and infrared spectra in a simulated(More)
Four amino cobalt phthalocyanine is well known as a promising photosensitizer. In order to enrich and complete the theoretical system of structural properties and reactivity, four amino cobalt phthalocyanine was synthesized and its ultraviolet-visible spectrum was obtained by experimental research. Then the experimental spectrum was compared with that(More)
With chitosan as the raw material, a new type of resin material is synthesized through epichlorohydrin crosslinking. The effects of the reactant ratio, the reaction temperature, the reaction time, the stirring rate and the system pH on the cross-linking rate are studied in detail. The resin material is then characterized by means of IR. The experimental(More)
