Sulfonated coal - semi - functional highly acid cation exchanger, contains in quality of ionizable group of sulfonate group, capable to exchange of ions with electrolytes. Sulfonated coal is made by sulphonation of black coals oleum.
Sulfonated coal is highly acid cation exchanger with the maintenance of sulfonate groups as ionogens. These sulfonate groups possess ability to ion - exchange process with electrolytes why sulfonated coal is used for water treatment: softening, desalting and decrease in alkalinity of water.
Besides, sulfonated coal can serve for decationizing from sewage, condensates and solutions with chemical pollution. It is important to know that sulfonated coal cannot be used in those conditions when there is need for receiving water of drinking quality.
During the work with sulfonated coal it is necessary to remember properties of combustibility. It is dotcndj is flame - resistant and it is capable to self - heating and ignition at contact with hot air. In case of self - ignition of its sulfonated coal it is necessary to extinguish quickly water or the fire extinguisher.
