Standard Test Methods for Total and Dissolved Carbon Dioxide in Water1 This standard is issued under the ﬁxed designation D ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. AFile Size: 94KB. Either dissolved or total recoverable copper may be determined. Determination of dissolved copper requires filtration through a μm () membrane filter at the time of collection. In-line membrane filtration is preferable. The values stated in SI units are to be regarded as standard. The values given in parentheses are.
METHOD POTENTIOMETRIC DETERMINATION OF SULFIDE IN AQUEOUS SAMPLES AND DISTILLATES WITH ION-SELECTIVE ELECTRODE SCOPE AND APPLICATION This method can be used for measuring total sulfide in a distilled sample. The method is meant to be used as an alternate determinative step following the distillation in either SW Methods . Common electrode types are pH, total dissolved solid (TDS), oxidation reduction potential (ORP), and ion selective electrode (ISE). They come in standard models or in all-in-one (sometimes called 3-in-1) models, which have a built-in temperature sensor for automatic temperature compensation (ATC).
An ion selective electrode used in the direct determination of water hardness in tap-water, has been fabricated using Mg(II)-N-phenylbenzohydroxamate complex in the membrane. The electrode characteristics exhibited almost equal selectivities for Ca2+ and Mg2+ which enabled the simultaneous determination of both the ions. chloride and ferrichloride with sulphide to form methylene blue [lo]. At pH a potentiometric titration with AgN03 was carried out using a sulphide-ion- specific electrode (Orion ) and a double junction reference cell (Ingold go-MS- NS).

The sulfide. the sulphide potential response of the electrode were tested by using the mixed solution technique  with a constant level of sulphide concentration 1x mol/L and increasing concentrations of anions in the range between and mol/L.
The anions have no influence in this concentration region on the measurement of sulphide. The know addition method and a new gas absorbing solution were investigated in thepotentiometric analysis of hydrogen sulfide with sulfied ion-selective electrode.
A NNaOH vol% glycerol mol/l EDTA -1 wt% L-ascorbic acid mixed solution was usedas a trapping (absorbing) solution for hydrogen sulfide (This solution inhibits the air. Rather than use the SIE sensor, the ATI dissolved sulphide monitor uses polarographic H2S gas sensor lowering maintenance & costs.
How it works: A small amount of sample is pumped into the system and mixed with acid. In acidic solution, hydrosulphide and sulphide ions (HS- and S-2) are converted to hydrogen sulphide.

An alkaline antioxidant reagent (AAR) is added to samples and standards to inhibit oxidation of sulfide by oxygen and to provide a constant ionic strength and pH.
Use of the AAR allows calibration in terms of total dissolved sulfide.
