硝基苯酚被视作严重的污染物,特别是对硝基苯酚(4-NP)和邻硝基苯酚(2-NP),作为制药工业的重要原料,它们在水中溶解性好、稳定性强,会对环境中的水体造成严重的威胁,因此,检测和监测水体中的4-NP和2-NP至关重要。利用水热法将巯基丁二酸作为碳源,制备出蓝色荧光碳点(MSA-CDs),在340 nm处激发,碳点在437 nm 得到最佳发射,荧光量子产率为32%,荧光寿命为9.65 ns。在本研究中,蓝色荧光碳点可以作为荧光探针,对4-NP和2-NP有特殊的响应,使碳点的荧光强度发生明显的减弱,检测限分别为18.3 nmol/L和24.0 nmol/L。该碳点可以在实际水样中检测4-NP和2-NP并得到较理想的回收率,说明碳点具备更为广泛的应用优势及可能性。
Nitrophenols are regarded as serious pollutants
especially 2-nitrophenol(2-NP) and 4-nitrophenol(4-NP)
deriving from processing and manufacturing as well as being used as raw materials for pharmaceutical industry. They have been proved as a crucial threat to environmental waters due to their good solubility
strong stability
high toxicity
and carcinogenicity. Blue fluorescent carbon dots(MSA-CDs) have been prepared by hydrothermal method using mercaptosuccinic acid as carbon resource. The CDs emitted blue fluorescence emission at 437 nm excited at 340 nm
with quantum yield(QY) of 32%. In this work
the CDs exhibited specific responses to 4-NP and 2-NP. CDs can be used as a fluorescent probe
and showed clear fluorescence quenching in presence of 4-NP and 2-NP with the detection limits of 4-NP and 2-NP at 18.3 nmol/L and 24.0 nmol/L
respectively. The CDs can be used to recognize 4-NP and 2-NP in actual water with high recovery
which indicates that the CDs exhibit more extensive application advantages and possibilities.
