Dual-functional pyrene implemented mesoporous silicon material used for the detection and adsorption of metal ions

A fluorescence “turn-on” probe for the detection of HSO3− based on a pyrene-functionalized mesoporous silica material

“…The synthesis of AAPTMS-SBA-15 and PYF was according to our previously reported work. 37,38 As shown in Fig. 1, 0.2 g of AAPTMS-SBA-15 in 25 mL of toluene was stirred for 0.5 h to get well-dispersed suspensions.…”

Utilizing sustainable hemp biomass as an eco-friendly for potentially toxic elements removal from water

“…It is known that PTEs such as Copper, Zinc, Lead, and Nickel are produced more than 1000 m 3 tons per year, and accordingly, their consumption values increase in this context [7,8]. As a result of increased exposure to PTEs, they affect human health negatively by penetrating into water resources [9]. Although PTEs such as Copper (Cu (II)) and Zinc (Zn(II)) are necessary for the metabolic activities of living organisms, the accumulation of PTEs in soil, organisms and humans at concentrations above their toxicity levels is a cause of great concern [10,11].…”

Poly(2-vinylpyridine)/MCM-41 Composites with Micropores and Switchable Mesopores for the Removal of Cr(VI)

“…7−9 Compared with other materials, mesoporous silica materials exhibit good capture to Cr(VI) based on its high surface area and porosity, low cost, simple preparation, and easy surface modification. 10−12 Organics (ethylenediamine, 13 pyrene, 14 etc. ), polymers (polyethyleneimine, 15 polyamidoamine, 16 etc.…”

“…Among Cr­(VI) pollution treatment technologies, − the adsorption technique possesses wider application potentials due to its low cost, high efficiency, simple process, and good regeneration ability. Carbon-based materials, natural mineral materials, mesoporous silica, organic framework materials, and biomass materials were used to trap Cr­(VI) in solution and exhibited excellent removal capacity. − Compared with other materials, mesoporous silica materials exhibit good capture to Cr­(VI) based on its high surface area and porosity, low cost, simple preparation, and easy surface modification. − Organics (ethylenediamine, pyrene, etc. ), polymers (polyethyleneimine, polyamidoamine, etc.…”
