				  Official Method of Analysis, Society of Leather Trades' Chemists, Fourth
				  Revised Edition, Redbourn, Herts., England, 1965 and is to be used for the
				  determination of sulfide in alkaline wastewater.
(1) OUTLINE OF METHOD.
(a) The buffered sulfide solution is titrated
				with standard potassium ferricyanide solution in the presence of a ferrous
				dimethylglyoxime ammonia complex. The sulfide is oxidized to sulfur. Sulfite
				interferes and shall be precipitated with barium chloride. Thiosulfate is not
				titrated under the conditions of the determination.
(b) Apparatus: burrette, 10 ml.

Current through June 24, 2024
(1) OUTLINE OF
				METHOD.
(a) Hydrogen sulfide is liberated from
				an acidified sample by distillation and purging with nitrogen gas (N2). Sulfur
				dioxide interference is removed by scrubbing the nitrogen gas stream in a pH 7
				buffer solution. The sulfide gas is collected by passage through an alkaline
				hydrogen peroxide scrubbing solution in which it is oxidized to sulfate.
				Sulfate concentration in the scrubbing solution is determined by either EPA
				gravimetric test procedure 375.3 or EPA turbidimetric test procedure 375.4 (see
				40 CFR
				136.3, Table IB, parameter 65 (49 FR 43234,
				October 26, 1984, and correction notice at 50 FR 690, January 4,

Wisconsin Administrative Code › Department of Natural Resources › NR 200-299 - Environmental Protection Wisconsin Pollutant Discharge Elimination System › Chapter NR 252 - Leather tanning and finishing › Section NR 252.0365 - Method detection limit method

Current through June 24, 2024
(1) DEFINITION.
				"Method detection limit" or "MDL" means the minimum concentration of a
				substance that can be identified, measured and reported with 99% confidence
				that the analyte concentration is greater than zero and determined from
				analysis of a sample in a given matrix containing analyte.
(2) SCOPE AND APPLICATION. This procedure is
				designed for applicability to a wide variety of sample types ranging from
				reagent or blank water containing analyte to wastewater containing analyte. The
				MDL for an analytical procedure may vary as a function of sample type. All
				sample processing steps of the analytical method shall be included in the
				determination of the MDL. The MDL obtained by this procedure is used to judge
				the significance of a single measurement of a future sample. The MDL procedure
				was designed for applicability to a broad variety of physical and chemical
				methods. To accomplish this, the procedure was made device or instrument
				independent.
(3) PROCEDURE.
(a) Make an estimate of the detection limit
				using one of the following:
1. The
				concentration value that corresponds to an instrument signal or noise ratio in
				the range of 2.5 to 5. If the criteria for qualitative identification of the
				analyte is based upon pattern recognition techniques, the least abundant signal
				necessary to achieve identification shall be considered in making the
				estimate.
2. The concentration
				value that corresponds to 3 times the standard deviation of replicate
				instrumental measurements for the analyte in reagent water.
3. The concentration value that corresponds
				to the region of the standard curve where there is a significant change in
				sensitivity at low analyte concentrations, such as a break in the slope of the
				standard curve.
4. The
				concentration value that corresponds to known instrumental
				limitations.

Current through June 24, 2024
(1) A POTW
				receiving wastewater from a facility subject to this chapter may require more
				stringent pretreatment standards for sulfide than those established by this
				chapter without EPA approval.
(2)
				The pretreatment standards for sulfide established by this chapter will not
				apply if the POTW receiving wastewater from a facility subject to this chapter
				certifies in writing with explanation of relevant factors considered, in
				accordance with the provisions of sub. (3) that the discharge of sulfide from
				the facility does not interfere with the operation of the POTW. In making this
				determination, the POTW shall consider all relevant factors including but not
				limited to the following:
(a) The presence
				and characteristics of other industrial wastewaters which can increase or
				decrease sulfide concentrations, pH, or both.
(b) The characteristics of the
				sewer/interceptor collection system which either minimize or enhance
				opportunities for release of hydrogen sulfide gas.
(c) The characteristics of the receiving
				POTW's headworks, preliminary and primary treatment systems, and sludge holding
				and dewatering facilities which either minimize or enhance opportunities for
				release of hydrogen sulfide gas.
(d) The occurrence of any prior sulfide
				related interference as defined in s.
				NR
				252.02(5).
