Abstract:
THE PRINCIPLE OF DISPERSION IS REVIEWED TO CLARIFY THE FUNCTION OF EACH STEP IN EXISTING PROCEDURES AND ALSO TO SERVE AS A BACKGROUND AND GUIDE FOR THE DEVELOPMENT OF A DISPERSION PROCEDURE FOR WISCONSIN LOESS. IN ADDITION, EXPERIMENTS WERE PERFORMED TO: (1) EVALUATE SEVERAL DEFLOCCULATING AGENTS, VIS., SODIUM METAPHOSPHATE, SODIUM PYROPHOSPHATE, SODIUM OXALATE, AND SODIUM SILICATE; (2) DETERMINE THE NEED FOR HYDROGEN-PEROXIDE AND HYDROCHLORIC-ACID TREATMENTS; AND (3) EVALUATE A RUBBER STIRRING PADDLE AND DETERMINE STIRRING TIME REQUIREMENTS, USING THE CONVENTIONAL HIGH-SPEED MALTED-MILK-TYPE MIXING APPARATUS. /AUTHOR/
