METHOD OF PURIFICATION OF GROUND, SOIL, CONCRETE AND BUILDING CONSTRUCTIONS FROM ORGANIC CONTAMINATION |
摘要 |
FIELD: chemistry. ^ SUBSTANCE: carbamide-formaldehyde polymer, for instance Penoizol, as toxicant sorbent from objects and washing are used. Ratio of purified object and sorbent is from 1:0.05 to 1:1 in volume or not less than 0.05 dm3 per 1 m2 of purified object surface. 0.5-1.5 wt % of sodium salt of polyacrylic, methacrylic acids or their mixture and 0.1-5.0% of sodium sulfate and/or silicate are added. Consumption of washing solution constitutes from 0.4 to 2.0 dm3 per 1 kg of soft ground or per 1 m² of hard ground surface, building constructions. ^ EFFECT: simplification and cheapening of purification; increase of safety of works on purification of objects from hydrocarbon contamination. ^ 1 tbl |
