Elimination of the contaminant fluoride ions from plant zinc sulfate electrolytes by aluminum sulfate

A novel “turn on” fluorescence probe based on a caffeic acid skeleton for detecting Al3+ and bioimaging application

“…As shown in Fig. S5, † probe HAM exhibited weak uorescence in different pH values (3)(4)(5)(6)(7)(8)(9)(10)(11). However, in the presence of Al 3+ (100 mM), probe HAM showed strong uorescence in the pH range of 3-11.…”

“…Job's plot showed that the binding stoichiometry between probe HAM and Al 3+ was 1 : 1. Compared with some reported probes, probe HAM exhibited a low limit of detection (0.168 mM) and wide pH work range (3)(4)(5)(6)(7)(8)(9)(10)(11). This study not only proposes guidance for the design and synthesis of new Al 3+ uorescent probes in the future but also provides a new idea for the efficient utilization of caffeic acid.…”

“…S4 †). The next study was to examine the effect of different pH (3)(4)(5)(6)(7)(8)(9)(10)(11) on the sensing behavior of probe HAM in the presence of Al 3+ . As shown in Fig.…”

“…Aluminium (Al) is one of the most abundant elements in the Earth's crust and plays a crucial role in many elds, such as papermaking, textiles, medicine, food additives, water purication systems, and construction materials. [1][2][3] Although aluminium is widely applied in many elds, from manufacturing industries to daily life, an excess of aluminium can cause harm to ecological, environmental and human health. For example, the accumulation of excess Al 3+ in soils can hinder the growth of plants.…”
