Verwenden
water is listed also as catalyzed, deionized, demineralized, distilled, pure spring, and purified water. Water is an important skin component and is essential for its proper functioning. It is the most common ingredient used in cosmetic formulations and, therefore, is generally listed first on product labels. Water is usually processed to eliminate hardness and minerals, and to avoid product contamination.
Definition
ChEBI: An oxygen hydride consisting of an oxygen atom that is covalently bonded to two hydrogen atoms.
Allgemeine Beschreibung
Water is widely used for HPCE (High-Performance Capillary Electrophoresis), luminescence and UV-spectroscopic studies.
läuterung methode
Conductivity water (specific conductance ca 10-7 mho) can be obtained by distilling water in a steam-heated tin-lined still, then, after adding 0.25% of solid NaOH and 0.05% of KMnO4, distilling once more from an electrically heated Barnstead-type still, taking the middle fraction into a Jena glass bottle. During these operations suitable traps must be used to protect against entry of CO2 and NH3. Water, only a little less satisfactory for conductivity measurements (but containing traces of organic material) can be obtained by passing ordinary distilled water through a mixed bed ion-exchange column containing, for example, Amberlite resins IR 120 (cation exchange) and IRA 400 (anion exchange), or Amberlite MB-1. This treatment is also a convenient one for removing traces of heavy metals. (The metals Cu, Zn, Pb, Cd and Hg can be tested for by adding pure concentrated ammonia to 10mL of sample and shaking vigorously with 1.2mL of 0.001% dithizone in CCl4. Less than 0.1Yg of metal ion will impart a faint colour to the CCl4 layer.) For almost all laboratory purposes, simple distillation yields water of adequate purity, and most of the volatile contaminants such as ammonia and CO2 are removed if the first fraction of distillate is discarded. Most laboratories have glass stills that “doubly” or “trebly” distil water. [See “water” in Chapter 1.]
