Abstract
The utility model relates to a portable ion detector, which is composed of a membrane frame, an ion exchange membrane and a guide head, wherein, the ion exchange membrane is arranged on the membrane frame; the guide head is connected into one body with one end of the membrane frame. Because the ion exchange membrane is used as the medium for extracting soil ions, also because the ion detector adopts the separate type structure of the membrane and the membrane frame, the utility model can be directly inserted into soil to do continuous or discontinuous profile detection; the sample detection is made to be more convenient, simple, time-saving, high-efficiency and low-cost. Simultaneously, the method of detecting the supply rate of ions in original position is not only simple and convenient but also sensitive and does not pollute environment.
Description
The utility model relates to a kind of ion detection device, belongs to natural resources and enviroment analysis instrument.
At present, the mankind are more and more deep to the understanding of natural resources and enviroment effect, are fully recognized that the importance of natural resources and enviroment quality.For example the soil nutrient supply is one of important indicator of soil quality, soil testing is effective method of estimating the soil nutrient limit and definite crop fertilization, the various soil testing methods of ion have been set up and used for many years, more advanced method is to adopt the way of extraction, as lime chloride extraction ammoniacal nitrogen and sulphur is the best index of plant available nitrogen and sulphur in the testing soil, measure exchange potassium and the widely accepted degree of phosphorus in the soil with calcium acetate (PH7) extraction, but all there is defective in various degree in these method of testings, can not comprehensive testing soil quality; A kind of desirable soil testing method should possess the condition of following three aspects: (1) extract should extract in the heterogeneity soil nutrient all or representational ratio, (2) Cui Qu soil nutrient quantitative measurement should have suitable precision and speed, and the quantity of (3) extraction should be relevant to the reaction of this nutrient with every kind of crop under the growth of crop and the various condition.And lime chloride extraction ammoniacal nitrogen and this method of sulphur are not considered the supply of nitrogen in the season of growth soil organism mineralising, Ammonium Acetate (PH7) method of extraction provides the index of the quantity of the potassium (or phosphorus) in the soil, but is not provided at the index of the quantity of known planting season of non-exchange potassium.Cui Qu way is owing to need quite to bother by a series of processes such as sampling, filtration, extractions simultaneously, and length consuming time is brought great inconvenience and restriction to field work.
It is dynamic and sampling determination is easy, time-saving and efficiency, ion detector that cost is low that the purpose of this utility model provides the ion of the comprehensive mensuration natural resources and enviroment of a kind of energy.
The utility model is made up of film frame, amberplex and seeker, and amberplex is installed on the film frame, and seeker and film frame one end link into an integrated entity.
Above-mentioned film frame is a right cylinder, and it is provided with a rhombus groove and rhombus flat key limit portion, and amberplex covers cylinder membranes frame surface and is fixed tightly on the film frame by the rhombus flat key.
Above-mentioned film frame is a rectangular parallelepiped, and the centre has through hole, and its two sides are provided with the installing port that communicates with intermediate throughholes, and amberplex is arranged on film frame core surface, and film frame inner core is arranged in the film frame intermediate throughholes by installing port.
The utility model is owing to adopt amberplex as the medium that extracts the soil ion; and amberplex adopts ion exchange resin to make; and ion exchange resin is similar to plant roots; like this in the utility model is placed into the soil; nutrient ion around the amberplex can be transferred into effective form and absorb the film surface; thereby be absorbed in the lip-deep nutrient ion of film and quantity can be regarded as the speed that the nutrient ion is supplied to plant; can utilize amberplex as the assessment soil nutrient content like this; assess a kind of more accurate of soil quality; cheap effectively instrument; also can be used as mensuration soil; body refuse; the potential bio-toxicity of beavy metal impurity in the S ﹠ W matter etc.; the instrument of agricultural chemicals and other harmful ion; by to the determining of beavy metal impurity, find out the guard method of soil and environment sustainable development.The ion detector of this structure is owing to adopt the detachable structure of film and film frame simultaneously, can directly insert and make continuous or discrete section mensuration in the soil, make sample detecting more convenient simple, time-saving and efficiency and cost are low, and can be connected by double-screw bolt one screw of its end face between the detector, realize the expandability of sampling.In sum, the utility model is the new technology that is used for assessing natural medium intermediate ion fill rat, new equipment, and it is very suitable for scientific research and aspect and other association areas such as agricultural, forest and environment.With the method for this device in-site detecting ion fill rat, both simple and fast was sensitive and free from environmental pollution again.
Describe basic structure of the present utility model and principle in detail below in conjunction with accompanying drawing:
