The theoretical yield of the method is less than 100%, as only 80 - 90% of the aqueous phase is removed after back-extraction. The actual yield obtained by 54 Mn counting was 69.5 7.8%, and this can be allowed for in the calculation of results. Environmental Protection Agency standard seawater samples of known manganese content (4370 ng/1) gave good manganese recoveries (4260 ng/1).

In the Tri-State region of Missouri, Kansas and Oklahoma, measurements of public supply wells have shown that the U.S. Environmental Protection Agency standard for radium concentration (5pCi/l) is exceeded in a number of locations. A part of the investigation into the cause of this health hazard is the study of the uranium isotopes, U and U, precursors of Ra.

Consider the issue of designing a recycle reactor to accomplish the degradation of 99.99% of the phenol present at a concentration of 1.1 x 10 M in supercritical water at 380°C and 278 atm. This destruction level is selected on the basis of Environmental Protection Agency standards for thermal treatment of hazardous organic wastes. The corresponding inlet concentration of oxygen is 0.08 M. Prepare a plot of the reactor volume required to process 8 m /h of the supercritical aqueous solution versus the recycle ratio for values of this ratio between 0 and 20. Comment. 

If selected options are electrochemical and are not covered by ENl504 then go to the relevant European Standard as given in Chapter 7 (or use a NACE national or government agency standard or specification if more relevant of if a suitable EN document does not exist).
