The purpose of this investigation was to study the
adsorptive and reactive properties of Saskatchewan volcanic
ashes. As an indication of the chemical reactivity of the
ashes, a test showing the reduction in alkalinity of a
sodium hydroxide solution in contact with the ashes and the
release of silica at the same time was performed on the
ashes. Similar tests were carried out on calcined samples
of two of the ashes. In addition, surface area measurements
were made on the ashes by the nitrogen adsorption.method,
since the surface area is an important factor in the
reactivity, adsorptive properties, and catalytic activity
of substances.
