“…The comparison is given in Table 2. Recently, many researchers have worked on determining manganese (II) ions in water, food, and vegetable samples using atomic absorption spectrometry, ultrasound-assis ted-dispersive-micro-solid phase extraction, or multi-walled carbon nanotubes [28][29][30][31], but the proposed method based on 5-Br-PADAP coupled to DP-CSV and ASV is simple, fas t, low cos t and accurate/precise results as compared to others. As a cheap ins trument and a simple procedure, our electrochemical method performs relatively well at a low cos t and detection limit.…”

In this study, manganese (Mn II) was determined in aqueous media by an electrochemical method, and its removal was evaluated using the aeration-filtration process (AFP). An electrochemical sensor based on carbon paste (EPC) modified with the 5-Br-PADAP ligand was used to measure Mn (II) in aqueous media. Through the optimization of analytical parameters in cathodic stripping voltammetry (CSV), real boreholes and well water samples could be analyzed for manganese content. The optimum parameters such as preconcentration potential (1100 mV), preconcentration time (240s), 5-Br-PADAP ligand concentration (20 µmol L-1), and electrode rotation speed during pre-concentration (1000 rpm) were studied and optimized. The detection limit (LOD) is estimated at 3 ´10-7 mol L-1 with a relative standard deviation (RSD) of 3.36%. The real samples showed that some water points have more concentration than the standard. A simple, effective, inexpensive, and rural-friendly method was used for treating manganese-rich water. Following the aeration phase, the sand and gravel column was filtered to remove manganese (II) from the water. The removal efficiency of Mn was obtained at a rate of 74.8- 84.5% and more than 95% after two hours of aeration and 1 hour at pH 8 for real samples.

It is always a concern to ensure personnel and environment safety in the field of chemistry which has caused to development of green analytical chemistry methods. Green chemistry aims to create an eco-friendly environment in laboratories by using various analytical methods/strategies to reduce the use of toxic solvents which are harmful to humans and the environment. It is a way that protect the environment by using green solvents and methods. Green analytical chemistry is a rapid analytical technique that describes the separation, identification, and quantification of an analyte in drugs, environments, and humans. Various green methodologies such as automation, miniaturization, precipitations, and passivation are utilized in the recovery of solvents and reagents. Green analytical chemistry aims to create an eco-friendly environment in the laboratories by using various analytical methods/strategies to reduce the use of toxic solvents which are harmful to the environment/humans as well as to decrease the amount of waste generated. In this review, we explore different green solvents that can replace other toxic solvents used during extraction processes. In this review, the various extraction methods and analytical techniques used to analyze different components have been discussed.
