In some embodiments, a method may include separating contaminants from impaired water. The method may include contacting impaired water with a peracetate oxidant solution. The method may include mixing said impaired water with the peracetate oxidant solution. The method may include separating the impaired water oxidant solution mixture into solids and a water phase. In some embodiments, the peracetate oxidant solution may include peracetate anions and a peracid. The peracetate oxidant solution may have a pH from about 10 to about pH 12. The peracetate oxidant solution may have a molar ratio of peracetate anions to peracid ranging from about 60:1 to about 6000:1. In some embodiments, a peracetate anion to hydrogen peroxide molar ratio is greater than about 16:1. In some embodiments, a reactive coagulant, a softener, and/or a floc aid may be added to the impaired water.

An easy-to-prepare chemosensor, 2-(4-formylphenyl) phenanthroimidazole 1, synthesized by facile onestep condensation under microwave irradiation, has been indicated to be a colorimetric and fluorometric probe for fluoride anion with good sensitivity and high selectivity. This probe shows obvious red shift and absorbance intensity changes in UV absorption and fluorescence spectra in the presence of fluoride anions. Such color and absorbance intensity changes are attributed to the deprotonation of N-H on the imidazole moiety with fluoride anion. © Springer Science+Business Media, LLC 2009.

Since lanthanides are inner transitional elements with their 4f and 5d energy levels closed, they possess narrow electronic absorption peaks, which are little affected by their chemical environment. In this research, a thermal lens microscope (TLM) that utilizing diode lasers as pump and probe beams was constructed for selective determination of Sm (III) without any pre-concentration and separation procedure. The calibration plot has a linear behavior over the 0.5-500 μg mL-1 range and a limit of detection (LOD) of 0.08 μg mL-1. The relative standard deviation (RSD) is smaller than 5%. This method can be potentially applicable to environmental studies. © 2015 The Korean Society of Industrial and Engineering Chemistry.
