What is the composition of bentonite? What are the uses? Price per ton?
The invention relates to a method for synthesizing organic bentonite by microwave. It is the surfactant cation according to the raw bentonite exchange capacity of 20 200%CEC dissolved in water, the quality of the solid-liquid ratio in the range of 1 to 5 to 1: 500, through adding dry, soil sieve bentonite, microwave reactor into 100 5000W microwave power, irradiation 10s 30min, filter, surfactant, wash free microwave drying, at 60 - 120 DEG. C drying, the drying time is 30min - 24hr, grinding and sieving to obtain organic bentonite. The invention has the advantages that: 1) the microwave synthesis of organic bentonite can greatly shorten the processing time of synthesis; 2) synthesis process is simplified, energy consumption is greatly reduced; 3) filtrate recycling, no surfactant containing wastewater; 4) organic bentonite stable product quality, the concept of uniform and low cost. Low, excellent adsorption performance, the removal of organic pollutants has good effect, high economic efficiency; 5) particularly suitable for sodium, calcium bentonite or acid clay was modified with cationic surfactant.
The invention discloses a method for treating organic waste water by microwave synergistic organic bentonite. It is the size of 40 - 200 orders of organic bentonite and organic wastewater mixed, the solid-liquid ratio was 1: 500: 1: 5000, then flows into a microwave reactor, a 200 5000W microwave power irradiation 10s 30min decolorization and purification, then. The liquid phase separation, waste water purification treatment after discharge. The advantages of the invention are as follows: 1) the purification time of waste water is greatly reduced; and 2, the pollutant removal efficiency is improved. As for the acid red dye wastewater by microwave irradiation after a certain period of time, the decolorization of CPC organic bentonite ratio can reach more than 99%, while the conventional adsorption removal rate is only about 60%; 3) the operation process is simple. Using microwave irradiation, without stirring, can simplify the operation process and enlarge the application prospect of organic bentonite.
For some demanding occasions, water can be washed to remove unwanted excess reactants and reactive salts, and then dried and ground to prepare high quality organic bentonite. Compared with the prior art, the invention has the advantages that the reaction may be 30 to 200 seconds to complete the required amount of ethanol, only for the traditional process of 5 ~ 10%, the quality of the products exceed the level of the traditional crafts; compared with the existing technology of dry, product quality is greatly improved.
Preparation of organic bentonite CN03126543 by microwave dryingThe invention relates to a production method of organic bentonite, the organic matter was soluble in ethanol aqueous solution, the reaction liquid is sprayed into the bentonite powder in the fully wet, then wet material evenly into the thickness of 2 ~ 20mm, 900 ~ 3000MHz frequency in micro wave field in rapid heating reaction, after the reaction can be obtained by crushing organic bentonite.
