7 .1-6 <br /> 5IU <br /> V- (20) (W) - 16(W) - A <br /> V- ml deionized water to be added <br /> W- weight in grams of solid charged to extractor <br /> A- ml of 0.5N acetic acid added during extraction <br /> 7 . The material in the extractor should be separated <br /> into its component liquid and solid phases as described <br /> under "Separation Procedure. " <br /> 8 . The liquids resulting from Steps 2 and 7 should be combined. <br /> This combined liquid (or the waste itself if it has less <br /> than 0.5% solids, as noted in step 2) is the extract and <br /> should be analyzed for the presence of any of the contami- <br /> nants specified in Table I of 40 CFR 261.24 using the <br /> Analytical Procedures designated below. <br /> Separation Procedure <br /> Apparatus <br /> A filter holder, designed for filtration media having a <br /> nominal pore size of 0 .45 micrometer and capable of applying <br /> a 5 .3 kg/cm2 (75 psig) hydrostatic pressure to the solution <br /> being filtered shall be used. For mixtures containing non- <br /> absorptive solids , where separation can be effected without <br /> imposing a 5 .3 kg/cm2 pressure differential, vacuum filters <br /> employing a 0.45 micrometer filter media can be used. <br />
