Fig. 1 is the structural representation of a kind of embodiment of ceruse content testing device of the present invention.
Embodiment
Combine accompanying drawing that the present invention is done further explain through embodiment below.
Embodiment one:
In the present embodiment, be used for first container and second container that accumulator plate ceruse determinator comprises gas collecting means, buret and open upper end with choana.This first container is positioned in the cavity volume of second container, and the opening of second container is higher than the opening of first container, makes that pure water can not have the opening part of first container when adding pure water.The end that this gas collecting means has a choana tips upside down on the opening part of first container; And cover the opening of first container basically; Be used for collecting the gas that produces from first container; Why this opening does funnel, is in order to increase the aperture area of gas collecting means, as far as possible all to absorb the gas that from first container, overflows.Leave spacing between the opening of this choana and first container, make that the liquid in second container can flow in the choana.This buret is communicated with the gas collecting means, and the gas of collecting in the gas collecting means can enter into buret.
Please refer to Fig. 1; In a kind of specific embodiment; The ceruse content testing device comprises first container 1, second container 2, gas collecting means 3 and buret 4, and first container 1 is the beaker of 100 milliliters of volumes in this example, and second container 2 is the beaker of 500 milliliters of volumes; This gas collecting means 3 adopts funnel 3, and buret 4 adopts acid buret 4.
This first container 1 is placed in second container 2, and the open upper end of its second container 2 is higher than the open upper end of first container 1, makes in second container 2, to add sufficient pure water, so that seal first container, 1 opening fully.The opening end of this funnel 3 tips upside down on the opening part of first container 1, and covers the opening of first container 1 basically fully, so that can collect the gas that from first container 1, distributes as far as possible.Keep certain spacing between the opening end of funnel 3 and first container 1, make funnel 3 inner with second container 2 between be communicated with, but the liquid between is mobile.The upper end sealing of this acid buret 4 and funnel 3 is communicated with, and is used to collect the volume with measurement gas.
Embodiment two
The application also discloses the ceruse assay method of determinator among a kind of embodiment of utilization one, and the method comprising the steps of:
