Tri-n-octylphosphine oxide (TOPO) is a chemical compound that is used in the treatment of wastewater. It is a white solid that has a melting point of 102 °C and an odor threshold of 0.05 ppm. TOPO reacts with citric acid to form sodium citrate, which is soluble in water. Sodium carbonate is formed when TOPO reacts with sodium hydroxide. This chemical also has synergistic effects with other chemicals, such as aluminum sulfate and ferric chloride, which are used for wastewater treatment. TOPO can be used to remove organic compounds from wastewater by oxidation reactions, such as methyl ethyl alcohols or methyl ethyl acetates. The reaction solution changes color from yellow to red during the oxidation process, which indicates the removal of these compounds from the solution. The reaction between TOPO and hydrogen peroxide produces heat and oxygen gas, which can be measured using calorimetry or spectrometry techniques.br>br

Ethyl Red [Not Cyanin Dyes]

Ethyl Red Indicator is a chemical species that exhibits fluorescing properties under the influence of radiation. It is used as a test compound in analytical chemistry to determine the presence of acidic or basic compounds in a solution. Ethyl Red Indicator has been shown to react with quinoline derivatives and form an active methylene group, which facilitates electron transfer. This reaction mechanism leads to an enhancement of fluorescence intensity. The rate of the reaction can be determined by measuring the time taken for the ethyl red indicator to change from red-orange to pink.

N-Ethyl-N-methyl-3-(pyrrolidin-3-yl)benzamidehydrochloride is a red fluorescent dye that is soluble in organic solvents. It has been shown to be reactive with metal ions and polymerization initiators, and is used as a reactive dye for polymers in detergent compositions. NEMB can also be used as an indicator for the presence of divalent hydrocarbons, such as hexane and acetonitrile. NEMB has been shown to have excellent solubility in both polar (e.g., water) and nonpolar (e.g., oil) media, making it suitable for use in many industrial applications.
