Fluorescent probe reagent for concurrent selection and determination of multiple metal ions, and preparation and appliance

The invention discloses a probe reagent for concurrent selection and determination of multiple metal ions, and preparation and appliance, and belongs to the field of organic synthesis and analytical chemistry. Tri (2-aminoethyl) amine serves as a parent, wherein rhodamine B is connected to an amino chain, 2-hydroxy-1-naphthaldehyde groups are connected to other two amino chains respectively, and thus a tripod structured rhodamine-hydroxyl naphthalene derivative probe is prepared. In 1,4-dioxane/water (19/1, v/v, pH=7) solution, the probe respectively detects Cu2+, Co2+ and Fe3+ by utilizing rate absorption of different wavelengths, and the detection does not interfere with each other; in acetonitrile/water (19/1, v/v) solution, fluorescence emission of different wavelengths under different pHs is utilized, the probe respectively detects Zn2+, Al3+, Hg2+ and Cu2+, and the detection does not interfere with each other; under an ultraviolet lamp of 365 nm, Zn2+, Al3+ and Hg2+ are detected to show blue, pink and orange red fluorescence respectively, and through -Zn2+ mixture detection by the probe, Cu2+ shows blue fluorescence vanishing. The probe structure is as follows.

Preparation method of slump loss resistant naphthalene water reducer

ActiveCN103864332AEnhanced controllability of molecular structureSave resourcesSodium metasilicateOrganic solvent
The invention discloses a preparation method of a slump loss resistant naphthalene water reducer. The naphthalene water reducer is prepared by sulfonating, hydrolyzing, condensing and neutralizing raw materials including crude naphthalene, naphthalene derivatives such as methylnaphthalene, concentrated sulfuric acid, formaldehyde, caustic soda liquid, water and the like. According to the production process, monomer substituents, such as methylnaphthalene and acenaphthene are introduced, an organic solvent azeotropic method is adopted for synthesizing, and finally sodium metasilicate is adopted for neutralizing to adjust pH to 7-10 to obtain the final naphthalene water reducer. The slump loss resistant naphthalene water reducer is prepared by the implementation mode disclosed by the invention, the crude naphthalene is replaced by partial naphthalene derivatives, an effective path of reducing the cost is proposed, naphthalene steam and a solvent are condensed to form a naphthalene solution to be recycled, and thus the product yield is improved and the environmental pollution is reduced.
