Adsorbent for removal of methyl blue from water solutions, method for producing it and regeneration

摘要

adsorbent for the removal of methylene blue from aqueous solutions is characterized by the fact that contains carbon nitride doped grafitopodobny with added inorganic salt metal block p. salt content is 0u00f720 wt%. the capacity of this material to the adsorbion equilibrium methylene blue is 650 mg / g adsorbenta.way to receive adsorbentu removal of methylene blue from aqueous solutions is characterized by the fact that the starting material is prepared as an aqueous solution of grafitopodobnego carbon nitride and inorganic salt, and after evaporation of solvent poddaw starting material ana's thermal polycondensation at a temperature 500u00f7750u00b0c in atmosphere nieutleniaju0105cej,then the material is purified distilled water, shake him. as a precursor to apply cyanamide or melamine. as the inorganic salt is sodium chloride in quantities 5u00f775 wt%. the precursor.way to regeneration adsorbentu removal of methylene blue from aqueous solutions is such that the waste material is subjected to a process fizykochemicznym, eliminating the zaadsorbowany methylene blue.used adsorbent treated distilled water having a temperature higher than 120 degrees for 24 hours or is subjected to continuous extraction liquid - solid soxhlet using water as ekstrahenta or basking in the 500u00b0c temperature for an hour, and then give up it is continuous extraction liquid - solid soxhlet using water as ekstrahenta.
