Flow-Injection Determination of the Total Water Hardness by Using a Copper(II) IonSelective Electrode and a Copper(II) Ion Buffer A potentiometric determination of the total water hardness by flow-injection analysis is proposed, which uses both a CU2+ ion-selective electrode detector ... T Ima...
waterultraviolet spectrophotometryA flow injection method (FIA) has been developed for the determination of chloride with Hg-EDTA complex as reagent. Spectrophotometric detection in the ultraviolet region at 250 nm was used for measuring the absorbance of [HgYCl]3 complex ion, where H4Y is EDTA. ...

A drawback of the prolonged stirring method is the need for precise timing and reproducible stirring as well as bleeding of reagents in the sample solution. Figure 1 (a) Chlorine gas hydrolyses in water to hypochlorous acid. (b) The ratio of hypochlorous acid to hypochlorite ion varies in ...
TC 178-TMC : TESTING AND MODELLING CHLORIDE PENETRATION IN Round-Robin test on chloride analysis in concrete- Part I : Analysis of total chloride content M Castellote,C Andrade 被引量: 27发表: 2001年 Round-robin test on chloride analysis in concrete — Part II: Analysis of water soluble ...
Over a period of 1 year, the surface water of a canal network (Languedoc-Roussillon area, France) was analysed in order to identify organic compounds and to monitor its quality. Pollutants were extracted from 19 l of raw water using methylene chloride in a continuous countercurrent liquid-...
The vast amount of plastic waste emitted into the environment is of increasing concern because there is mounting evidence for various toxic effects of microplastics on living organisms. In particular, despite freshwater ecosystems are essential sources of water supply, they have been less investigated ...
Retrieval of these variables with a broad range of spatial and temporal scales has become one of focuses in the field of quantitative remote sensing. The ratio of the imperviousness to the total area is considered a significant urban ecological index in the fields of urban hydrology, water ...
the analysis of the evolution of the main hydrogeochemical parameters of the groundwater showed that the increased pumping rates produced an increase in total dissolved solids, and chloride and sodium ions in both aquifers. In the case of the Lora aquifer, the only ion that presented decreased ...
