“…Polymeric surfaces coated with few other dyes have also been investigated by some other researchers as a possible chemical dosimeter [65][66][67][68]. The ionizing radiation-induced bleaching of disazo (Direct) dyes dissolved in Cellophane was mainly attributed to a reduction involving reactive transient radiolytic species, mainly thermal electrons.…”

“…Therefore, the development of a sensitive and reliable method is essential for the determination of BG in various water samples. Several methods such as adsorption, chemical oxidation, dosimetry and membrane processes have been reported for the determination and removal of this dye (Robinson et al 2001;Santhy and Selvapathy 2006;Lin and Lin 1993;Georgiou et al 2003;Sarasa et al 1998;Allegre et al 2006;Fersi et al 2005;Khan et al 2002). Most of these methods are expensive and require time-consuming and complicated instruments.…”

A new and simple method for the determination of trace amounts of brilliant green was developed by coacervative extraction and spectrophotometry. The method is based on the extraction of brilliant green with coacervates made up of sodium dodecyl sulfate as an anionic surfactant, in the presence of saturated NaCl solution. The effect of various experimental parameters such as pH of solutions, concentration of surfactant and concentration of salt was investigated using central composite design based on response surface methodology. Under the optimum conditions the calibration graph was linear in the range of 0.03-2.2 µg mL −1 with a detection limit of 0.012 µg mL −1 . The relative standard deviation for seven replicates of 1.2 µg mL −1 brilliant green was 1.75%. The proposed method was successfully applied for the determination of brilliant green in different real samples including fish farming water, river water and tap water samples.

“…Some chemical radiation research using dyes, such as light green, 10 thymol blue, 11 need to be conducted in the absence of light because light will influence the stability of the dye and interfere with dose measurements. We tested the sensitivity of TH solutions towards light.…”

This research investigated the ionizing radiation effect on thiamine hydrochloride (TH) and its usability as an irradiation dosimeter. The fundamental principle is to determine the concentration variations of TH solutions with high-performance liquid chromatography (HPLC) after exposing to γ-rays. The decreasing peak area of TH in the HPLC chromatogram forms a linear relationship with the rising radiation dose. We investigated the characteristics and suitable application range of the TH as a new radiation dosimeter. The influence factors and mechanism of the reaction induced by radiation were also discussed. According to the correlation between the concentration and the radiation dose, 0.3 g/L of a TH solution is suitable for the 0.1 -10 kGy dose range, and 2 g/L is appropriate for 0.1 -20 kGy. The easy availability and the simple, but stable, chemical structure of thiamine makes it a potential candidate for radiation dose research. Also, the preparation proceeding for sampling is easy, and the result can be automatic monitored by liquid chromatography.
