Embodiment
Below, by specific instantiation explanation embodiments of the present invention, those skilled in the art can understand other advantages of the present invention and effect easily by the disclosed content of this instructions.The present invention can also be implemented or be applied by other different embodiment, and the every details in this instructions also can be based on different viewpoints and application, carries out various modifications or change not deviating under spirit of the present invention.
Be described in more detail of the present invention below in conjunction with diagrammatic cross-section, wherein represented the preferred embodiments of the present invention, should be appreciated that those skilled in the art can revise the present invention described here, and still realize advantageous effects of the present invention.
Shown in Fig. 1, it is titration apparatus 100 structural representations of a kind of potentiometric titrimeter in the embodiment of the present invention.Described titration apparatus 100, includes a stirrer 10, is vertically provided with a tubulose Dropper stand 110 on described stirrer 10; On described tubulose Dropper stand 110, be arranged with a chuck 111, in described chuck 111, sandwich 112 be housed, in described sandwich 112, insert solenoid valve 130, and by the fixing described solenoid valve 130 of branch head screw 113; Also include a curved shape Dropper stand 120, described curved shape Dropper stand 120) through sandwich 112, and 120 of described curved shape Dropper stands are fixedly connected with a buret 140 by buret fixed screw 122, described curved shape Dropper stand 120 bottoms are also folded with electrode holder 123, and the bottom of described electrode holder 123 is arranged with collar 124; Described solenoid valve 130 tops be provided with proofed sleeve 141, and described proofed sleeve 141 is inserted in buret 140 ends.
Known, the principle of work of potentiometric titrimeter is as follows: in titration process, along with adding of titrant, owing to treating, between measured ion and titrant, chemical reaction occurs, ion concentration to be measured constantly changes, and causes also corresponding changing of indicator electrode current potential.Near stoichiometric point, ion activity to be measured is undergone mutation, and the current potential of indicator electrode is corresponding undergoing mutation also.Therefore,, by measuring the variation of cell emf in titration process, can determine titration end-point.During finally according to titrant concentration and terminal, titrant consumption volume calculates component concentration to be measured in test solution.
Install after titration apparatus 100 of the present invention, in concrete operation steps, in buret 140, pour standard titration solution into, the proofed sleeve of solenoid valve 130 141 is rinsed 3 ~ 4 times with the standard titration solution in buret 140, in buret 140, pour standard titration solution into again, and buret 140 liquid levels are adjusted to 0.00 scale, then get a certain amount of test solution in test glass, in test glass, put the stirrer that people cleaned, then test glass is placed on stirrer 10; Selection processing, cleaning electrode, then by electrode holder on electrode holder 123, and electrode tip is immersed in test solution; Terminal is set " setting " switch is put to " terminal ".
In sum, the titration apparatus of a kind of potentiometric titrimeter of the present invention, not only apparatus structure is simple, and has improved detection efficiency greatly.So the present invention has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all can, under spirit of the present invention and category, modify or change above-described embodiment.Therefore, such as in affiliated technical field, have and conventionally know that the knowledgeable, not departing from all equivalence modifications that complete under disclosed spirit and technological thought or changing, must be contained by claim of the present invention.
