| titleOfInvention | Process for preparing of silica gel |
| abstract | Usage: the invention can be used to obtain silica gel. capable of extracting proteins, peptides, nucleic acids and metals from wastewater and dilute solutions. SUMMARY OF THE INVENTION The alkali metal silicate solution is mixed in which permanganates or chromates are pre-dissolved. or alkali metal bichromates in an amount of 0.5-33 mol.% of the amount of silicate and an acid solution into which oxalic acid is introduced, or a hydrazine salt or a transition metal salt in a lower valence state, or both alkali metals in a stoichiometric amount of with respect to permanganates or chromates or dichromates, they are washed and dried. 2 s.p. f-ly. |
