Orange IV is a surfactant that is used to remove nitrogen from wastewater. It has been shown to be effective in removing nitrogen from wastewater, and can be used as a substitute for sodium dodecyl sulfate (SDS). Orange IV has been shown to have similar properties as SDS, but does not contain any sulfur atoms.

The surface methodology for this surfactant includes flow assay, which uses fluorescence spectrometry and synchronous fluorescence. Fluorescence spectrometry involves measuring the amount of light emitted by a substance when irradiated with light of a certain wavelength. Synchronous fluorescence involves using two lasers with different wavelengths to measure how quickly or slowly molecules react with each other. In this case, it measures how quickly or slowly Orange IV reacts with other substances in order to determine

Alcian Yellow stains are usually visible on skin surfaces and may indicate the presence of fungal infections or dermatitis. Alcian Yellow can also be used for diagnosis purposes, such as detecting cancerous lesions or diagnosing skin conditions, including acne or psoriasis.

Acid blue 120 is a polymer film that is used for wastewater treatment. It removes organic pollutants from water by binding to them and has been found to be effective in removing phenols, amines, and ammonia.

Acid blue 120 can be used for the removal of proton-transporting materials such as carbonyl groups from aqueous solutions. This process may be optimized by controlling the particle size or using radiation to activate the polymer film.
