In one embodiment, be provided with identical cell body in the both sides of Test paper.Two cell bodies are set, contribute to improve the absolute quantity that is adsorbed onto the ion in test paper, this contributes to improve the detection speed of test paper.In one embodiment, the degree of depth of cell body and the Length Ratio of described test paper are 1: 5-1: between 7.Cell body is rectangular parallelepiped, and its length and width are than 3: 5-3: between 7.

In one embodiment, Test paper is strip, and its length is 5-7 centimetre, and width is 0.5-0.7 centimetre.In a preferred embodiment, the length of Test paper is that 7 centimetres, width are 0.5 centimetre, and the cell body degree of depth is that 1 centimetre, width are that 0.3 centimetre, length are 0.5 centimetre.In the test paper of this structure, the length of cell body equates with the width of test paper, and this contributes to simplify the production of test paper.In addition, the length of this test paper and width all equate with length and the width of the test paper of other types, and this has also facilitated production and the use of test paper.

According to second aspect of the present utility model, a kind of mercury ion detecting test paper has been proposed, it has Test paper structure mentioned above.

In one embodiment, the detection material of detection layers is rhodamine B.Rhodamine B is in the time running into mercury ion, under white light, visual inspection is bright-coloured aubergine, and under ultraviolet light, be bright-coloured orange red, and its color is along with the concentration of mercury ion raises and grow, these features can help user's fast detecting go out to detect mercury ion in thing with and concentration range.

Compared with prior art, the utility model has the advantage of, be provided with cell body at the free end of test paper, solution to be measured can be joined in cell body.The ion that can make like this solution carry wherein spreads along test paper for a long time, thereby contributes to detect the ion in solution.In addition, being set to its length by test paper is that 7 centimetres, width are 0.5 centimetre, and groove depth is that 1 centimetre, width are that 0.3 centimetre, length are 0.5 centimetre.In the test paper of this structure, the length of cell body equates with the width of test paper, and this contributes to simplify the production of test paper, and the length of this test paper and width all equate with length and the width of the test paper of other types, and this has also facilitated production and the use of test paper.

Accompanying drawing explanation

To be described in more detail the utility model based on embodiment and with reference to accompanying drawing hereinafter.Wherein:

Fig. 1 is the structural representation according to Test paper of the present utility model;

Fig. 2 has shown the structural representation of cell body.

In the accompanying drawings, identical parts use identical Reference numeral.Accompanying drawing is not according to actual ratio.

Embodiment

The utility model is described in further detail will to engage accompanying drawing below.

Fig. 1 has schematically shown according to the structure of Test paper 10 of the present utility model in the mode of zoomed-in view.Test paper 10 comprises test paper matrix 11, is provided with detection layers 12 on test paper matrix 11.Test paper matrix 10 can be material common in prior art, such as filter paper, nonwoven fabrics etc., and these are all that those skilled in the art is known.The first end 13 of Test paper 10 is set to handheld terminal, and in process of production, this first end 13 is for encapsulation; And in use, this first end 13 is as handheld terminal.The second end 14(of Test paper 10, free end) be set to test lead, be provided with the cell body 15 for holding solution at the second end 14 places.To be described in detail cell body 15 hereinafter.

In order to detect exactly the ion in solution, detection layers 12,12 ' can be all set on two of test paper matrix 11 side.In addition, diaphragm 16,16 ' can also be set respectively in

detection layers

12,12 '.Diaphragm 16,16 ' can be protected Test paper 10, prevents that it is contaminated and lost efficacy before use, more importantly, can also avoid the impact of the ion pair accuracy of detection in external environment in testing process.
