The reception of humic derivatives with increased sorption ability on mineral matrixes
The results of reception and research of the humic substance fixed on a mineral matrix-silicate in the process of humate extraction by the water solution of sodium silicate are presented in the paper. The basic conditions of process are optimised in the course of researches. The composition of the received composite is characterised by means of IR-spectrometry and thermogravimetric analysis. The optimum conditions of process of reception of silicate humate are following: concentration of sodium silicate – 2%, process temperature – 30-40°C, of the silicate humate dealkalization process duration – 30-40 minutes, coal particles dispersity – 0-3 mm to 0-5 mm.
