Problems solved by technology

Because the colored solution contains cobalt, nickel, copper, iron and other soluble ions and the color of the solution is unstable, the turbidity analyzer is greatly disturbed and cannot be accurately analyzed and judged
With the gravimetric method, when there are many soluble substances, the filter membrane is difficult to clean, and the weighing will cause a large error, and the operation requirements are high and complicated, so it is not suitable for rapid measurement during production

Embodiment Construction

[0022] 1. Preparation of standard turbidity solution.

[0023] 1. Weigh 10g of diatomite that passed through a 0.1mm sieve (150 mesh) into a mortar, add a little distilled water to make a paste and grind it finely, transfer it to a 1000mL graduated cylinder, add water to the 1000mL mark, stir well, and let stand 24h; use the siphon method to transfer 800mL of the upper suspension to the second 1000mL graduated cylinder, add water to the second graduated cylinder to 1000mL, stir well and then let it stand for 24h.

[0024] 2. Siphon out the 800mL suspension containing finer particles in the upper layer, discard it, add water to the bottom flow (ie the lower part) sediment to dilute to 1000ml, stir well and store in a stoppered glass bottle to obtain a suspension.

[0025] 3. Take 50.0mL of the suspension above and place it in an evaporating dish with constant weight, evaporate to dryness on a water bath, dry in an oven at 105°C for 2 hours, cool in a desiccator for 30 minutes, ...

Abstract

The invention relates to an analytical method for detecting the micro solid suspended particle content of colored solution. At present, the turbidity of the colored solution is generally analyzed by two methods, namely the turbidity analyzer analytical method and the gravimetric analysis. But a turbidity analyzer is easily interfered, cannot accurately analyze and judge the turbidity, has high requirements on operation, is complex in operation and is not suitable for quick detection during production; and under the condition that the gravimetric analysis is adopted, a filter membrane is difficult to be cleaned and big error is caused when weighing. In the method of the invention, a clean leachate or a clean deironed liquid serves as a base liquid; a standard liquid with corresponding turbidity is prepared from the base liquid; the absorbance is measured through a spectrophotometer; and the turbidity is calculated by comparing the absorbance with the measured absorbance of sample solution. By the method, the result can be quickly analyzed and the analytical error caused by colour interference can be avoided.

Description

technical field [0001] The invention relates to an analysis method for the turbidity of a colored solution, which is used for measuring the content of tiny solid suspended particles in the colored solution. Background technique [0002] In wet smelting, solid-liquid separation is carried out after immersion slurry and iron-removing slurry are thickened, clarified, and filtered, and then organic extraction is carried out. Because organic extraction has high requirements for the solid content in the solution, it is necessary to extract the solution after solid-liquid separation. The content of solid suspended particles is measured to judge the effect of separation to guide production. [0003] There are generally two methods for the analysis of the turbidity of colored solutions: turbidity analyzer analysis and gravimetric method. Since the colored solution contains cobalt, nickel, copper, iron and other soluble ions and the color of the solution is unstable, the turbidity an...
