METHOD FOR COLLECTING OIL WITH MODIFIED CLAY

摘要

The present invention provides a method for collecting oil with a modified clay. By mixing the modified clay and oil, the oil can be adsorbed to the clay. The modified clay is obtained by intercalating a hydrophobic polymer such as acidified poly(oxyalkylene)-amine into layered silicate clay, mica or talc to enlarge the interlayer space. The modified clay thus becomes hydrophobic and adsorption to the oil is promoted.
