Designed by the leaders in UV-Visible Spectroscopy for molecular absorption quantitative analysis, the UV-1280 Multipurpose UV-Visible Spectrophotometer offers wavelength scanning from 190-1100 nm. This lower-cost, high-quality instrument is ideal for applications ranging from routine environmental and food quality testing to life science analyses.
Inorganic Ions and Metals-Environmental water
In the environmental sector, there are regulations that ensure monitoring for quantities of specific substances in industrial wastewater and river water. In the United States, EPA method 218.6 specifies a method for analyzing dissolved hexavalent chromium in drinking water, ground water, and industrial wastewater. EPA Methods 300.0 and 300.1 specify an analysis method for inorganic anions in water by ion chromatography (IC).
An increase in the concentration of phosphorus and nitrogen in river water can cause abnormal growth of algae and photoplankton. We describe using thie UV-1280 water analysis program to analyze day-to-day changes in pohosohate-hosphorus levels in river water and residual chlorine, iron, and total hardness levels in tap water.
Many countries and regions specify standard values for general inorganic anions such as fluoride, chloride, nitrate, nitrite, and sulfate ions in order to minimize the potential health effects of environmental water and drinking water.
In the United States, Environmental Protection Agency (EPA) Methods 300.0 and 300.1 specify the analysis method for inorganic anions in water by ion chromatography (IC). An EPA 300-compliant quantitative analysis of 7 general inorganic anions in various types of water samples was conducted using an HIC-ESP, which is a Shimadzu ion chromatograph system equipped with an electrodialysis-type suppressor.
The method for analyzing dissolved Cr(VI) in drinking water, groundwater, and industrial wastewater is described in EPA 218.6. This article demonstrates analysis of Cr(VI) with the Shimadzu Prominence Inert System.
Dissolved Cr(VI) is separated by an anion exchange column. The colored complex formed between Cr(VI) and diphenylcarbazide in the post-column derivation is then detected at 530 nm.
The HIC-ESP is a new anion suppressor ion chromatograph with built-in electrodialytic suppressor, boasting the same low carryover and excellent injection precision characteristic of Shimadzu HPLCs to bring you highly-reliable results.
