Spectrophotometric determination of some phenols with sodium metaperiodate and aminophenols

Active-Site-Rich 1T-Phase CoMoSe2Integrated Graphene Oxide Nanocomposite as an Efficient Electrocatalyst for Electrochemical Sensor and Energy Storage Applications

“…The intake of Metol-contaminated water can cause several health problems such as skin allergies, eye irritation, and damage to internal organs of the human body . There are some analytical methods such as spectrophotometry, liquid chromatography, ceric oxidimetry, photometry, and electrochemical sensor. − Among the all, electrochemical sensor is an effective method for the detection of Metol due to its easy sample preparation, less cost, sensitivity and selectivity . Therefore, we believed that the electrochemical sensor is a suitable method for the determination of Metol.…”

Ultraviolet and light absorption spectrometry

“…3-Methylbenzothiazoline-2-one hydrazone has been recommended as a reagent for the spectrophotometric determination of 17 pharmaceutical phenols including para-unsubstituted, parasubstituted, and o-dihydroxyphenols (119). Another paper devoted to the determination of phenols has suggested the use of two pairs of reagents: m-aminophenol and periodate ion for catechol, catecholamines, eugenol, and guaiacol, and metals and periodate ion for pyrogallol, gallic acid, phloroglucinol, and butylated hydroxyanisole (453). Extraction and photometric determination of substances containing the sulfhydryl group have been accomplished by extracting their ion associates of Rhodamine 6Zh and Astra Phloxine cations with hexachloroantimonate(III) from buffered aqueous solutions into toluene (464).…”
