15、 United Kingdom. BS EN 15216:2007EN 15216:2007 (E) 4 Introduction Total dissolved solids are a common sum parameter which is in use in water analysis and in analysis of eluates. TC 292 and TC 230 cooperated on this item to create one horizontal standard which is of most practical use for laboratorie

16、s. BS EN 15216:2007EN 15216:2007 (E) 5 1 Scope This European standard specifies a method for the determination of total dissolved solids (TDS) in water and eluates, provided they are not volatile under the conditions specified or that they do not release water molecules from hydration. It applies to

17、 water and eluates containing more than 200 mg/l of total dissolved solids. Samples with lower amounts of dissolved solids can be analyzed by repetition of the drying step. 2 Terms and definitions For the purposes of this document, the following term and definition applies. 2.1 total dissolved solid

18、s TDS TDSmass of dissolved constituents per unit volume of water remaining after a specified filtering and drying process NOTE TDS is expressed in milligrams per litre. 3 Principle The test sample is filtered and then dried in a dish to a constant mass in an oven at (105 3) C. 4 Sample storage and p

19、reparation During storage, the laboratory sample may be subject to changes which are liable to influence the analysis result. If storage is necessary, samples shall be kept at (4 2) C. NOTE Freezing should be avoided due to risk of formation of precipitation. It is recommended to carry out the test

20、immediately after sampling of the water sample or preparation of the eluate. 5 Equipment 5.1 Drying system thermostatically controlled and capable of maintaining a temperature of (105 3) C; e.g. drying oven, infrared system. 5.2 Desiccator with an active drying agent such as silica gel. 5.3 Analytic

21、al balance with an accuracy of 1 mg or better. 5.4 Membrane filter (porosity of 0,45 m). 5.5 Filtration apparatus. 5.6 Evaporation dish or crucible. Temperature tolerant laboratory vessel withstanding 105 C. Suitable materials are glass, ceramic, porcelain, aluminium and other materials inert to the

22、 test portion. BS EN 15216:2007EN 15216:2007 (E) 6 6 Procedure Filter the test sample through the membrane filter as specified in 5.4 unless it has been membrane filtered before (e. g. eluates prepared according to EN 12457). Dry the dish, for example in the oven, at (105 3) C and weigh to the neare

23、st 1 mg (to obtain ma) after cooling to ambient temperature in the desiccator. Homogenise and transfer a proper aliquot (VFB) if necessary in stages, into the dish to ensure that not less than 20 mg and not more than 1 000 mg of dry mass, mD, remains after evaporation to dryness. Evaporate the sampl

24、e to dryness by a drying system according to 5.1 and weigh to the nearest 1 mg (to obtain mb) after cooling to ambient temperature in the desiccator. The mass of the dry matter, mD, shall be considered constant if, after drying for a further half-hour period, the mass obtained does not differ by mor

25、e than 0,5 % of the previous value or 2 mg whichever is the greater. Otherwise, drying shall be repeated until constant mass has been reached. NOTE If a constant value is not obtained even after drying for a third time, record the value determined last and note this in the test report. 7 Calculation

26、 of results Calculate the total dissolved solids from equation (1): FBDTDSVm= (1) with mD= mb mawhere TDSis the concentration of total dissolved solids, in mg/l; mDis the mass of the dry matter, in mg; mais the mass of the empty dish, in mg; mbis the mass of the dish containing the dry matter, in mg

27、; VFBis the volume of the filtered test sample taken, in l. Values shall be rounded to the nearest 1 mg/l. 8 Quality control Where uncertainty exists about the homogeneity or behaviour of the sample, it is recommended that the analysis is carried out in duplicate.
