A portable breathing apparatus for oxygen enrichment of breathable air comprises: an adsorption vessel; an air compressor for pumping air into the adsorption vessel; a valve for purging pressure from the adsorption vessel; an adsorbent disposed within the adsorption vessel adsorbing a non-oxygen constituent of air when the vessel is pressurized, thereby producing oxygen-enriched air, and desorbing the non-oxygen constituent when the pressure is purged.

The specification relates to a clay having kaolinite from 20-40 wt. %; illite from 15-30 wt. %; pigeonite from 5-15 wt. %; and quartz up to a maximum of 40 wt. %. The clay is for use as an agent for reducing concentration of phosphorous in a fluid. Also disclosed is a process for preparation of a modified clay, and a method of treatment of a fluid using the clay or modified clay. 1. A clay , the clay comprising:kaolinite from 20-40 wt. %;illite from 15-30 wt. %;pigeonite from 5-15 wt. %; andquartz up to a maximum of 40 wt. %,wherein the clay is for use as an agent for reducing concentration of phosphorous in a fluid.2. The clay of claim 1 , further comprising:nontronite from 1-5 wt. %.3. The clay of claim 1 , further comprising:nontronite from 1-5 wt. %, and dolomite from 1-8 wt. %.4. The clay of claim 1 , further comprising:aluminum, calcium, iron potassium, magnesium or sulfur up to a maximum of 15 wt. %.5. The clay of claim 1 , wherein the phosphorous is an inorganic ionic phosphorous species.6. The clay of claim 5 , wherein the inorganic ionic phosphorous species is a phosphate ion.7. The clay of claim 1 , wherein the phosphorous is glyphosate.8. The clay of claim 1 , wherein the fluid is water.9. The clay of claim 1 , wherein the clay is a zirconium modified clay or an iron modified clay.10. The clay of claim 1 , wherein the clay has a D(90) of from 100-150 μm.11. The clay of claim 1 , wherein the clay is heat treated at a temperature between 400° C. and 800° C. over a period between 30 minutes to 48 hour.12. The clay of claim 11 , wherein the clay is granulated prior to heat treatment.13. The clay of claim 11 , wherein the clay is granulated after heat treatment.14. A method of treatment for reducing the concentration of phosphorous in a fluid claim 11 , the method comprising:contacting the fluid with a clay, or modified clay, comprising:kaolinite from 20-40 wt. %;illite from 15-30 wt. %;pigeonite from 5-15 wt. %; andquartz up to a maximum of 40 wt. %.15.
