Process for the preparation of stabilized chlorine dioxide solution consists of; a) diluting 12.0~17.0 wt% sodium perchlorate solution with water, b) generating chloride dioxide by adding 0.1~1.0 wt% NaOH with 0.2~1.0 wt% phosphate salts... AHN, JOON-CHAN,KIM, YONG-HAN,KIM, SUNG-KI,......
The invention discloses a preparation method of a chlorine ion adsorbent. The preparation method comprises the following steps: (1) preparing a mixed water solution containing Fe3+, Fe2+, and Ni2+; (2) dropwise adding an ammonia water solution into the mixed water solution to carry out ...
A green but efficient synthesis approach for chlorine-doped reduced graphene oxide (Cl-RGO) was developed. The chlorine-doping and reduction was achieved in one-step by refluxing graphene oxide solution in concentrated hydrochloric acid (8 M, 120 °C) under N2atmosphere. X-ray photoelectron spect...
Step 3: After the replacement in step 2 is completed, introduce chlorine gas to carry out the chlorination reaction; Step 4: Inject chlorine gas into step 3 for chlorination for 30 minutes and then filter to obtain a high concentration POLYETHYLENE, CHLORINATED solution; Step 5: Enter the POLY...
Process for producing an aqueous solution comprising ferric chloride The present invention provides a process for preparing an aqueous solution of FeCl.sub.3. The process involves the steps of: (a) reacting an ore material comprising titanium and iron with chlorine and coke to form a metal chlori...
with cubic crystal structure. Use of all the additives refined the granularity of the alumina product, improved the solution conductivity, and increased the chlorine content in the alumina product. Addition of HCl improved the recovery rate of Al, but use of the additives Na2CO3and NaHCO3greatly ...
Both the downstream processing of silicone and the high-end cleaning industry require hexamethyldisiloxane products with low silanol content and low chlorine content. In addition, hexamethyldisilazane is widely used in pharmaceutical industry, gas chromatographic analysis, bonding aid for photoresist in ...
Typically, a solution of the sulfide compound in the solvent is prepared and cooled to the desired reaction temperature. Approximately one molar equivalent of chlorine or bromine is added. After a short reaction period, the N-([1,2,4]triazolopyrimidin-2-yl)amine compound is added, and the ...
Here we'd like to present our new results about the controllable preparation of nano-gold catalyst by fine tracing the chlorine con- centration of the aqueous solution, which contains the precipitated catalyst precursors, in the range of 0 to hundred ppm, in the washing step. A classical ...
