Speciation of Mn(II) and Mn(VII) by on-line spectrophotometric sequential injection analysis

Sequential injection system with multi-parameter analysis capability for water quality measurement

“…Several extended devices can be incorporated to the SIA, e.g., gas diffusion unit for conductometric determination of ammonium [3], ion exchange column, resin packed columns and so on, which help to improve performance of the system. It is ideally suitable for process or environmental monitoring [4][5][6][7]. The SIA system was used extensively in the multi-parameter analysis.…”

Determination of Manganese in Environmental Samples by UV-Vis after Cloud Point Extraction

“…Human who exist in a high concentration of manganese ion in the environment for a long-term can cause interference of mental and emotions and slow, clumsy physical actions [5]. Therefore, it is important to determinate the trace amounts of Mn in various matrices samples for certain areas, such as environmental chemistry and food processing [6].…”

Speciation of Mn(II), Mn(VII) and total manganese in water and food samples by coprecipitation–atomic absorption spectrometry combination

“…The most prevalent oxidation states of manganese are Mn(II) and Mn(VII). Speciation of Mn(II) and Mn(VII) is necessary for evaluating the toxicological behavior of manganese [9][10][11].…”
