“…After 1990's observed that, the perchlorate detection rang was decrease from 400µg/L to 4µg/L [2] and going near about 1.05µg/L [28] because researchers are modified many detection and separation techniques. Perchlorate is more stable compound due to that more difficult to reduce and it is an easily mobilized compound in atmosphere because it have inherent characteristics.…”

“…The Perchlorate water treatment technologies have been evolved into Present-day. The Recent Review of different technologies used for the treatment of Perchlorate was revealed in 2018.These Techniques grouped into three categories: Chemical treatment, Physical treatment, nZVI material treatment [2]. Perchlorate used as an electrolyte with high oxidizing property and many different applications but it plays a role of health hazards material in the environment.…”

“…The Thyroid gland hormones play an important role in the human body for Central Nervous System, Skeletal System, Metabolism and Growth, most essential role in the Fetuses and Birth Outcomes [3], [4]. Perchlorate can be produced by atmospherically and by the natural resources like fertilizers, due to thus generate some environmental problems and pollution diffusion [2]. Due to the great water solubility and lower adsorption [5], Perchlorate ions are hard to degrade and remove from environment.…”

“…When ClO 4 anion concentration is high in polluted water, cost of perchlorate reduction using bioremediation technique comparatively low. Reverse to this, when Perchlorate concentration is in fewer amounts in contaminated sample, enzymatic reduction is very costly because need of large reducing medium [11] and rate of reaction is comparatively slow [2].…”

Perchlorate is a highly toxic compound. It has both chemical and physical properties. Perchlorate is not easily degradable compound by both bio and non-bio degradation process because of its high stability, highly water soluble compound and low absorption. That’s why perchlorate reduction becomes a big challenge. In this research work we studied different type of electrochemical technique and effect of different electrodes on these techniques. In present days, many techniques were developed for the detection or reduction of perchlorate such as bio-degradation, optical, chemical, electrochemical and microbial technique. This article gives information about application of electrochemical technique for the detection or reduction of perchlorate. The electrochemical techniques have various types for the detection of ion. These techniques grouped on the behalf of various types of electrical signal such as potential or voltage, current and impedance which were produce in the presence of perchlorate into aqueous solution. Electrochemical technique such as impedance spectroscopy, this technique was performed on the electrochemical work station by applied a constant range of frequency. In cyclic voltammetry technique we were given a constant potential range and found results in the form of oxidation and reduction current. In the reduction of perchlorate history various researcher was found results using different electrochemical technique on different types of electrodes. The perchlorate salts and perchlorate have some useful application in the defense field, batteries, automobile airbags, rocket propellants and fuels. Perchlorate contamination is become a worldwide health problems. In many western states perchlorate was found in ground and surface water. It disturbs the thyroid gland to uptake iodine the human body. So its prevention technique was needed. However, the electrochemical techniques have more advantage such as low cost, user friendly, label free and real time monitoring over all other techniques. So we focus on electrochemical detection technique for the perchlorate.

The production of oleic‐based trimethylolpropane (TMP) esters via the esterification reaction between oleic acid (OA) and TMP in a reactive distillation system, employing the environmentally friendly catalyst methanesulfonic acid, was explored. The homogeneous acid catalyst, the OA/TMP molar ratio within 1.0–3.0, the esterification reaction enhancement and a new purification technique, using choline hydroxide (ChOH), for obtaining choline carboxylate as a subproduct, were studied. It was found that using an OA/TMP molar ratio of 3.0, only unreacted OA remained as an impurity. The deleterious or beneficial effect of intermediate products, unreacted OA and temperature on the kinematic viscosity were unraveled. The kinematic viscosity behavior for the products was practically independent of temperature but an abrupt enlargement of the kinematic viscosity was observed in the presence of functional groups in the intermediate esters, even greater than the Mark–Houwink counterpart effect. On contrary, the presence of OA in the final product decreased the kinematic viscosity attending to its lower molecular weight with respect to the trimethylolpropane trioleate one. It was found that trimethylolpropane monooleate is undesirable for the viscosity index, whereas the presence of trimethylolpropane dioleate could also increase the viscosity index to a small extent, requiring a complex purification process. Finally, it is possible to affirm that the optimal TMP‐based lubricant obtained using an OA/TMP molar ratio of 3.0, after OA neutralization presented good marginal benefit and a viscosity index of 208.7, which is applicable for gear lubricants. © 2022 The Authors.
