Analysis of potassium chloride purity

Catherine Shoff  Follow
Yes, it is determined by the capacity method, simple and accurate, measure the content of potassium ions, and use sodium borne sodium boric acid drip solution. The principle is that tetrazene and sodium sodium will be combined with potassium ions to produce precipitation.

The method I searched online, in fact, our accuracy of analysis results is not high within 5%. Can you help me see this method feasible?

The current method of determining potassium content is mainly tetrazene -boron sodium or sodium nitrate diamond weight method and atomic absorption method, and the instrument is directly measured. The accuracy of the weight of potassium is high, and the analysis error is about 2%of the scholars, but the measurement fee is required, and the more expensive drying and weighing equipment is required; the use of the atomic absorption method can quickly measure the potassium. The equipment required for this method is expensive and difficult to promote, and it is limited to the measurement of trace potassium. The soil fertilizer detector can directly measure the content of potassium in the fertilizer. The instrument uses the optical method. After a few minutes of operation, the instrument prints the detection report on the spot to obtain the results.

The traditional laboratory method requires professionals to do standard curves for manual computing, and only suitable for inspection professionals with rich experience. It requires high temperature heating or digestion of acid. The use of the test vehicle is used, and the traditional laboratory method also needs to purchase imported instruments. The price cost is high. What's more, it can only go out a series of shortcomings such as test reports and long measurement results. The soil fertilizer detector avoids these problems. The methods are simple and fast. Non -professional will also use it. It also adapts to the professional test laboratory. The soil fertilizer detector does not have the price of imported instruments abroad. On average, the measured sample is within 10 yuan, which is more suitable for laboratory use testing.

In addition, tetrazene -boron potassium ratio is a high method of rapid measurement of potassium. This method adopts the principle of tetraphnophyll sodium sodium and potassium or money reaction to generate four -stupid boron potassium or tetraphnibene boron -to -money precipitation. Under certain conditions, a high -efficiency flocculant is used to make the tetrazene, boron potassium or tetrazene boron ingredients scattered in the solution scattered in the solution. The sediment is quickly condensed and floats to the upper part of the special reaction bottle to form a fixed height. This Figure 1 height 1 is proportional to the potassium or in the measured solution. The content of potassium in compounds.

In this analysis method, because the generated tetrazene boron potassium or tetraobenzene boron disclosure precipitation is a floccope and scattered in the solution, which cannot form a fixed height, it is not possible to form a high -efficiency flocculant. The object is quickly condensed and floated to the surface of the solution, and then using the high method to determine the technology is the key to technology. The high -efficiency flocculant may be organic or inorganic. This method uses polypropylene amine.

It is necessary to point out: 1. The height of the sediment changes over time, and the time is reduced. Therefore, the reading time during the measured measurement should be consistent with the number of reading when the standard curve is made, otherwise it will produce it. Error; 2. When the cross -sectional area of \u200b\u200bthe reaction bottle changes, the height of the sediment changes accordingly, so the reaction bottle of the same specification should be used when measured and doing standard curves; 3. The standard curve of potassium and the standard curve of the measurement money cannot Universal. The selected high -efficiency flocculant will also make the standard curve difference; 4. The difference in the temperature of the solution will cause the height of the sediment to change, so the temperature during measurement and standard curve isTry to be as consistent. The reaction bottle is best made of transparent glass to facilitate observing the response in the bottle and measure the height of the sediment.

Because the tetrazene and boron sodium does not respond to the high -efficiency flocculant, in order to speed up the analysis speed, these two solutions can be stored in a reagent bottle and the reaction precipitation mixture can be matched. When using it, add the fertilizer to the mixture directly to make the potassium or ions in the solution precipitate and quickly float to the liquid surface to form a fixed height. However, this reaction precipitation mixture should not be stored for a long time, and in the use, only excessive tetrazene and sodium sodium solution can be added to make the potassium ions in the solution completely forming a precipitation.

This method can be used to quickly and accurately determine the content of potassium or pressed in various chemical fertilizers (or compounds, mixtures). Suitable for potassium fertilizer or fast and accurate analysis of potassium materials, intermediate products, and final products in the process of nitrogen fertilizer production. This method is simple and fast. The analysis error is about 4%of the scholars. The required instrument and equipment is only about 20 yuan. The measurement of the material consumes only 0.20 yuan each time, which has a good promotion and application value.
