<br /> Bilge water(X) 2.0 Summary of Method.
<br /> Boiler cleaning waste(X,C) 2.1 Organolead is separated from the sample matrix by extraction with
<br /> Bunker Oil(X,I) xylene.The organolead in the extract is reacted with Aliquat 336 and io-
<br /> Catalyst(X,I,C) dine and the solution is made up to volume with MIBK.Lead contained
<br /> Caustic sludge(C) in this mixture is determined by flame atomic absorption spectrometry
<br /> Caustic wastewater(C) (FAAS).If the original sample is completely soluble in xylene,the ex-
<br /> Cleaning solvents(I) traction step is omitted.
<br /> Corrosion inhibitor(X,C) 3.0 Safety.
<br /> Data processing fluid(I) 3.1 Some organic lead compounds are volatile and toxic. Therefore,
<br /> Drilling fluids(X,C) samples must be processed in a well-ventilated hood. Antiknock lead
<br /> Drilling mud(X) compounds are particularly poisonous and must not be inhaled or in-
<br /> Dyes(X) gested or come into contact with the skin. Antiknock lead compounds
<br /> Etching acid liquid or solvent(C,I) should never be exposed to elevated temperatures (above 50°C) or to
<br /> Fly ash(X,C) acids and oxidizing agents.Whenever organic lead compounds are han-
<br /> Fuel waste(X,I) dled outside of a well-ventilated hood,protective respiratory equipment,
<br /> Insecticides(X) protective clothing and rubber gloves must be wom.The material safety
<br /> Laboratory waste(X,C,R,I) data sheets(MSDS)for organolead standards must be read.
<br /> Lime and sulfur sludge(C) 3.2 The solvents used in this method are flammable. Proper precau-
<br /> Lime and water(C) tions must be taken to prevent contact with sparks or open flames(other
<br /> Lime sludge(C) than the AAS flame).
<br /> Lime wastewater(C) 4.0 Interferences.
<br /> Liquid cement(I) 4.1 To reduce loss of organic lead compounds which are very volatile
<br /> Mine tailings(X,R) and sensitive to oxygen,samples must not be exposed to elevated temper-
<br /> Obsolete explosives(R) atures or to air for extended periods of time.Such losses shall be mini-
<br /> Oil and water(X) mized by adhering to the sample collection, preservation and handling
<br /> Oil Ash(X,C) procedures in subdivisions 7.2-7.4 and 8.1.1 of this appendix.
<br /> Paint(or varnish)remover or stripper(I) 4.2 If the samples are moist,there may be poor wettability with xylene.
<br /> Paint thinner(X,I) 5.0 Apparatus and Materials.
<br /> Paint waste(or slops)(X,I) 5.1 flame atomic absorption spectrometer(FAA spectrometer) with
<br /> Pickling liquor(C) background corrector and recorder or integrator;
<br /> Pigments(X) 5.2 lead hollow cathode lamp or electrodeless discharge lamp;
<br /> Plating waste(X,C) 5.3 nebulizer with impact bead;the standard rubber gasket in the nebu-
<br /> Printing Ink(X) lizer must be replaced with a cork gasket because the organic solvents
<br /> Retrograde explosives(R) used in this method attack rubber;
<br /> Sludge acid(C) 5.4 air,acetylene and appropriate AAS burner head;
<br /> Soda ash(C) 5.5 erlenmeyer flasks,250 ml and 100 ml,with ground glass stoppers;
<br /> Solvents(I) 5.6 mechanical shaker;
<br /> Spent acid(C) 5.7 glass filter funnel and filter paper(Whatman#40,#42 or equiva-
<br /> Spent caustic(C) lent);
<br /> Spent(or waste)cyanide solutions(X,C) 5.8 separatory funnels,250 ml capacity;
<br /> Spent mixed acid(C) 5.9 volumetric flasks,250 ml, 100 ml,and 50 ml.
<br /> Spent plating solution(X,C) 6.0 Reagents.
<br /> Spent sulfuric acid(C) All solvents and reagents must be at least analytical reagent grade,if
<br /> Stripping solution(X,I) available.
<br /> Sulfonation oil(I) 6.1 xylene(use p-xylene if available);
<br /> Tank bottom sediment(X) 6.2 methyl isobutyl ketone(MIBK,4-methyl-2-pentanone);
<br /> Tanning sludges(X) 6.3 iodine solution:dissolve 3.0 g of elemental iodine in toluene and
<br /> Toxic chemical toilet wastes(X) make up to 100 ml with the same solvent.Store in a brown bottle in a re-
<br /> Unrinsed pesticide containers(X) frigerator;
<br /> Unwanted or waste pesticides-an unusable portion of active ingredi- 6.4 Aliquat 336 (Tri-capryl methyl ammonium chloride), available
<br /> ent or undiluted formulation(X) from Aldrich, Milwaukee, WI, or from McKesson Co., Minneapolis,
