Problems solved by technology

[0018] Therefore all existing technologies are chemical methods, wherein a large amount of chemical reagents need to be used, the recovery rate is not high, there is pollution, and the operation is complicated
However, traditional chemical extraction methods cannot be applied to the removal of arsenic from yellow phosphorus because there is no conventional solvent for yellow phosphorus.

Embodiment Construction

[0125] The present invention will be described in the form of specific implementation below. However, the data of the examples should not be construed as any implicit or obvious limitation to the scope of the present invention.

[0126] The device of the embodiment

[0127] The apparatus of the example is shown in FIG. 1 . Because phosphorus is flammable, all operations must be done underwater. The dimensions of the apparatus of the example are 60x42x30 (cm).

[0128] The heater is shown in Figure 3. All components are illustrated in Figure 3. For a steady movement of the heater over the sample rod, eg a speed-controlled motor can be used.

[0129] The heater is the most important part. It is an electric heating wire wrapped around an aluminum tube. The aluminum tube wrapped around the heating wire is embedded in the plastic block as a whole (as shown in Figure 4 below). There is a thermocouple in the center of the heater to control the temperature of the heater. The ...

Abstract

The present invention relates to zone heating and smelting and molecular diffusion process to purify solid matter, such as yellow phosphorus via eliminating As. By means of zone heating and smelting and molecular diffusion, As content in yellow phosphorus is lowered while lowering the content of other impurities. In addition, no any pollution will be produced in the operation.

Description

technical field [0001] The invention relates to the purification of solid-containing impurities by the regional heating and melting molecular diffusion method, for example, the purification of yellow phosphorus, especially the removal of arsenic from the yellow phosphorus. Background technique [0002] Phosphorus is an essential element for living organisms. In the human body, phosphorus is the sixth most important element. Phosphorus is 1.2 grams per kilogram of body weight. Phosphorus exists in the form of hydroxyapatite in human bone, and its main component is adenosine triphosphate (hereinafter referred to as ATP). ATP is the energy carrier of all active cells. The beating of the heart and the movement of muscles are inseparable from ATP. The progress of life is accompanied by the regeneration of ATP. Phosphorus plays an important role in the energy production process of muscle movement. [0003] Phosphorus is a very important element in organisms, and the phosphoru...
