... The main iron species that act as coagulants is nanocrystal Fe(III) oxide/hydroxide, produced through Fe(VI) reduction. The use of ferrate as a coagulant in water treatment and polluted water containing inorganic chemicals, such as thorium, cyanide, and thiocyanate [11][12][13][14]. ...

... mgL À1 ). The analytical features of the proposed preconcentration system were compared with several of the previously published methods [41][42][43][44][45][46][47][48]. As shown in Table.5, our method is characterized by low cost, reproducibility, high sensitivity and selectivity. ...

... The kinetic spectrophotometric methods are known as sensitive methods for element quantification (Muller et al., 1980). By studding red-ox reactions of permanganate with organic compounds (Petković et al., 2007), (Micić et al., 2006), it is noticed that tungsten has performed inhibitory effect on the oxidation of 4-hidroxycoumarine by KMnO 4 in the presence of hydrochloride acid (pH 1.2-2). The reaction was recorded spectrophotometrically, based on measuring the decrease in the absorbance of the solution. ...

... Trace metals are toxic for many organisms above a threshold concentration (for instance, the maximum containment level of copper is 1.3 mg/L according to EPA and WHO), and thus the presence of these metal ions in the environment and the food must be precisely and periodically monitored, making its determination in various media an essential analytical task [1][2][3][4]. Copper is one of the essential trace elements, and it has a high importance in industry, environmental and biological systems since it plays central roles in many biochemical processes. Copper is considered to be the second most toxic metal to aquatic life, and it leaks to waters and to other ecosystems via wastewaters emanating from mining industries, refineries, paper and dyeing industries to name a few industrial sources, posing a high risk to public health. ...

... Several analytical methods were applied to vineyard soil characterization [16] with particular attention paid to Cu contents [17,18], whose detection is particularly important also in wine analysis [19,20]. However, to the best of our knowledge there are no comparative heavy metal assessments taking into consideration contemporarily 1-vineyards subjected to Cu-based phytosanitary treatments; 2-adjacent control plots; and 3-adjacent former vineyards where grapevine cultivation was discontinued tens of years before the study. ...

... The results of the present study are shown in Table 1. LOD of the present work is comparable or better than some previous studies for the determination of As(III) ions [22][23][24][25][26] . ...
