Cesium selective polymeric membrane sensor based on p-isopropylcalix[6]arene and its application in environmental samples

Abstract

The present work deals with developing a highly selective membrane electrode based on p-isopropylcalix[6]arene for accurate determination of trace amounts of cesium cations.

Mineralization of mefenamic acid from hospital wastewater using electro‐Fenton degradation: Optimization and identification of removal mechanism issues

“…As seen, the satisfactory degradation efficiency of close to 90% was achieved for the initial solution pH of 2 and 3 after 10 min. However, the degradation efficiency diminished up to 12% in the alkaline condition, where the solution pH was equal to 12, which could be attributed to the superior decomposition of H 2 O 2 as revealed in the following interactions: …”

Kinetic study of hydroxyl radical formation in a continuous hydroxyl generation system

“…At present, the main detection methods are chemical uorescence method, 17 uorescence, 18 electron spin capture, [19][20][21][22][23] chromatography, 24 and so on. [25][26][27][28] Some of these methods require expensive instruments, and some operations are very complicated. In this paper, the combined electrochemical and redox method was employed to measure the hydroxyl radical concentration, making the measurement of concentration of hydroxyl radicals in the kinetic experiments simple and efficient.…”

A systematic study and effect of PLA/Al 2 O 3 nanoscaffolds as dental resins: mechanochemical properties

“…Nanocomposites as a new material in nanotechnology science have attracted the extensive attention of researchers [1] and recent development on the market [2,3] in medicine aims at using equipment [4,5] to enhance prevention of diagnosis [6,7]. Tissue engineering [7][8][9], one of the important challenges in the tooth-restoration interface is polymerization shrinkage of composite resins [8,[10][11][12], such as nanoparticles and nanocomposites due to low molecular weight particles can solve this problem [13][14][15]. Nanocrystals based on dental resin composites contain filler particles with size less than 100 nm (0.1 lm) have improved restorative composite resin against wear and fracture and are claimed to provide increased aesthetics, strength and durability in dental restorative materials [16,17].…”
