Problems solved by technology

These methods provide a new technical solution for the research on the modification of non-metallic mineral materials, but the disadvantages are that the technical solutions used are still relatively complicated, and the raw materials used need to undergo specific processing, which is not conducive to large-scale development and utilization of low-cost non-metallic mineral materials. Application of metal mineral materials in water pollution control, disposal and treatment of solid waste, remediation of soil heavy metal pollution, prevention and control of nuclear pollution and nuclear waste, improvement of surface water and groundwater quality, etc.
[0006] There have been reports on various mineral clays using acid activation, salt activation, organic modification and other processing technologies and the application of their products. And its preparation method and application have not been reported

Embodiment 1

[0058] Example 1: A wet preparation method of attapulgite clay-based xanthate sodium salt

[0059] The wet preparation method of described attapulgite clay-based xanthate sodium salt comprises the following steps:

[0060] (a) The raw materials used and their weight proportions are: attapulgite clay 100kg, sodium hydroxide solid (chemically pure) 12kg, carbon disulfide 20kg, tap water 150kg. The attapulgite clay was taken from a mine in Jingyuan, and after crushing, sieving, grinding, purification, dehydration and drying, a powder product of 70-200 meshes was obtained;

[0061] (b) In the stirred reactor, first add water and sodium hydroxide according to the proportion of step (a), stir and dissolve, then add carbon disulfide liquid according to the proportion of step (a), the temperature is controlled at 5-30 ° C, and then Add attapulgite clay while stirring according to the proportion of step (a), continue stirring for 20 minutes to make it evenly mixed, and control the rea...

Embodiment 2

[0064] Example 2: A dry method for preparing attapulgite clay-based xanthate sodium salt

[0065] The dry preparation method of the attapulgite clay-based xanthate sodium salt comprises the following steps:

[0066] (a) The raw materials used and their weight proportions are: attapulgite clay 100kg, sodium hydroxide solid (60 mesh) 60kg, carbon disulfide 100kg, water 100kg. The attapulgite clay is taken from a mine sample of Jiangsu Jiuchuan Company. After crushing, screening, grinding, purification, dehydration and drying, a powder product of 70-6000 meshes is obtained;

[0067] (b) In the high-speed heat dissipation kneader, now sodium hydroxide and water in the step (a) are added to the kneader, stirring and dissolving becomes a concentrated alkali solution (also can be replaced with an equivalent amount of 37.5% industrial liquid alkali), and the temperature is lowered to After the temperature is below 30°C, add all the remaining raw materials in step (a), stir thoroughly...

Embodiment 3～12

[0069] Examples 3-12: A preparation method of attapulgite clay-based xanthate

[0070] For the preparation method of the attapulgite clay-based xanthate, the attapulgite clay used is 100kg, the other raw materials used and their weight ratios are shown in Table 1, and the preparation method is the same as in Example 1 or Example 2 is the same.

Description

technical field [0001] The invention belongs to chemical materials, and mainly relates to clay-based xanthate and a preparation method and application of clay-based xanthate. Background technique [0002] The heavy metal ion scavenger is an organic substance with a chelating functional group that can selectively capture, separate, and precipitate specific metal ions from a solution containing metal ions. The chelating precipitation method utilizes the ability of the chelating agent to interact with Hg 2+ 、Cd 2+ 、Cu 2+ , Pb 2+ , Mn 2+ 、Ni 2+ , Zn 2+ 、Cr 3+ The characteristics of rapid reaction of various heavy metal ions, such as water-insoluble chelating salts and larger alum flowers, so as to achieve the purpose of trapping and removing heavy metal ions. If a small amount of organic or (and) inorganic flocculant is added, an excellent settling effect can be achieved. At present, the heavy metal ion scavengers that are widely used in practical research mainly include...
