Tetrabromo-2,3-naphthophthalocyanine zinc（Ⅱ）（ZnNcBr4） was synthesized by refluxing 6-bromo-2,3-dicyanonaphthlene with anhydrous zinc chloride in n-amyl alcohol in the presence of 1,8-diazabicyclo[5,4,0]-undec-7-e...Tetrabromo-2,3-naphthophthalocyanine zinc（Ⅱ）（ZnNcBr4） was synthesized by refluxing 6-bromo-2,3-dicyanonaphthlene with anhydrous zinc chloride in n-amyl alcohol in the presence of 1,8-diazabicyclo[5,4,0]-undec-7-ene. The product was characterized by elemental analysis and IR. The absorption spectra in non-aqueous solvents and the thermal stability of the compound were studied. Its nonlinear optical limiting was explored by a double frequency Nd:YAG pulse laser system with wavelenth of 532 nm and pulse width of 8 ns and 23 ps.展开更多

It was found that the amount of adsorption of Zn2+depends mainly on pH value of the solution, added inorganic ions and containing Oxygen groups on the surface. The activated charcoal was treated with oaldation-negativeionizing (OA) method in order to produce more containing oxygen groups on the surface.The adsorption amount of Zn2+ on the treated activated charcoal increased remarkbly. Itwas also found that the more times the activated charcoal was treated, the moe powerfulthe acidity of the surface, and the larger the adsorption amoUn of Zn2+, so the chargedgrorps on the surface of activated charcoal are considered as the main adsorption activatedsites for inorganic ions. The adsorption characteristics of various complexes of Zn2+ onthe surface of activated charcoal have also been investigated. Three types of adsorptionnconfiguration of the complexes of Zn2+ on the surface of activated charcoal were suggestedaccording to the experimental results.展开更多
