Dispersing Agents for Particle-Size Analysis of Soils

Chelating agents such as DTPA and EDTA (Fig 4) are relatively large organic molecules that are able to bind metals (Tana and Lehtinen 1996) They are increasingly used with peroxide and ozone bleaching of wood pulp and discharged with spent bleach liquors He is responsible for the application technology of water-based paint systems and leads innovation projects with focus on high performance additives such as wetting- and dispersing agents emulsifiers and specialties such as Genamin Gluco 50 Jrg Rger worked for 15 years as lab manager at the company Schulz Farben Germany His main activities were product development creation of a POS

A role of humic matter and ore oxidation in rheology of

Eight oil sands ores were tested in order to quantify the levels of humic acids in these samples through the alkali extraction test originally developed to determine the oxidation of bituminous metallurgical coals The test gives a concentration of humic acids released from ores which in combination with the measurement of the total organic carbon content in the alkali extracts provides a

PARTICLE-SIZE ANALYSIS OF NATURAL SOILS 195 8 1 1 Disaggregation and removal of cementitious material in soils The minerals in clay soils are often joined together into aggregates which resist dispersion with a tenacity that varies with the factors responsible for the bonding Unless the aggregations are broken down small minerals which properly belong to the clay-size range may be

1 Introduction [2] It is widely accepted that the abrasion of the soil surface by saltating quartz sand is the most prolific way in which mineral dust is produced [Gillette 1977] The rate and spatial variation of dust production derived from the impact of quartz sand saltators are largely controlled both by the erodibility of the surface (surface roughness aggregate size distribution
