A kind of method of preparing multiple mixed solution with pure salt

Abstract

The invention relates to a method for preparing a multi-component mixed solution with pure salt, comprising the following steps: (a): dissolving various pure salts respectively to prepare multiple single solutions of equal mass concentration, and the mass concentration is the multi-component mixture to be prepared. (b): Press-filter each single solution and then transport it to its respective storage container; (c): Then transport the solution in each storage container to its respective constant-volume container; ( d): Then, the solutions in the multiple constant-volume containers are input into the mixing container according to the volume ratio, and stirred evenly to obtain a multi-component mixed solution; wherein the volume ratio is the mass ratio of the metal elements in the multiple single solutions. The method of the invention has a simple process and can only detect the concentration of each single solution to determine the concentration of the multi-component mixed solution, which greatly improves the detection accuracy, reduces the analysis and detection workload, and prevents liquid dispensing errors.

Description

technical field [0001] The invention relates to a preparation method of a multi-component mixed liquid, specifically a method for preparing a multi-component mixed liquid with pure salt, and belongs to the technical field of wet chemical industry. Background technique [0002] At present, the preparation of multi-component mixed liquid generally adopts dry process, that is, solid powder, gas and solid powder, liquid steam and gas, solid powder and other raw materials are used to react to prepare the target substance. During the production process, if the seal is not If it is strict, it will cause a lot of dust pollution. Generally, the temperature and pressure required by the dry method are relatively high, and the equipment is relatively large. In the current multi-component solution preparation process, the method used is to first measure a fixed volume of solvent according to the required concentration, then calculate the mass of the solute according to the required conce...

[0002] At present, the preparation of multi-component mixed liquid generally adopts dry process, that is, solid powder, gas and solid powder, liquid steam and gas, solid powder and other raw materials are used to react to prepare the target substance. During the production process, if the seal is not Strict, it will cause a lot of dust pollution, the general dry method requires higher temperature and pressure, and the equipment is relatively large

In the current multi-component solution preparation process, the method used is to first measure a fixed volume of solvent according to the required concentration, then calculate the mass of the solute according to the required concentration, then weigh the corresponding mass of solute, and dissolve it in the solvent at the same time. However, because the concentration of the solution needs to be measured after the preparation is completed, to see whether the preparation is accurate, because the current method can only detect the concentration in the mixed solution, there is a problem of mutual interference in multi-element detection, which seriously restricts the detection accuracy In addition, the detection steps are complicated and the detection cycle is very long; moreover, the detection of multi-metals mixed together requires element separation, first detect the easily detectable ones, and then reduce the easily detectable components by the metal content, once the detection is abnormal , the whole result is not informative
