Abstract

Various amine-functionalized polyacrylonitrile fibers (PAN_EF, PAN_PF, PAN_BF, PAN_NPF, and PAN_DNPF) were prepared and employed to detect and adsorb 1,4-benzoquinone. After comparing the different types of amines and different carbon chain lengths, the most evident color change was observed in PAN_NPF. This material possessed a suitable carbon chain length, strong alkalinity, and an adsorption capacity of up to 1.32 mol mol⁻¹. Following its immersion in a 1,4-benzoquinone solution for 30 s, PAN_NPF rapidly changed from yellow to dark brown. This interaction between amine and 1,4-benzoquinone was quick, rendering this approach effective for real-time monitoring. Moreover, PAN_NPF was highly effective in detecting 1,4-benzoquinone in water across a wide pH range (3–10), with a detection limit as low as 0.5 ppm. PAN_NPF maintained its sensitivity and underwent stable color changes even at low temperatures (0 °C), and the presence of ions and compounds in practical applications did not interfere with its discoloration behavior. The kinetic and isotherm curves revealed that the adsorption process was consistent with the Langmuir isothermal adsorption and pseudo-second-order kinetic models, demonstrating the chemical adsorption of 1,4-benzoquinone by PAN_NPF. These findings highlight the superior detection capabilities of PAN_NPF, rendering it an efficient and reliable material for environmental monitoring and water purification.

胺功能化聚丙烯腈纤维对1,4-苯醌的比色识别和吸附

制备了多种胺功能化聚丙烯腈纤维（PANEF、PANPF、PANBF、PANNPF和PANDNPF），并对1,4-苯醌进行了检测和吸附。比较不同类型胺和不同碳链长度后，PANNPF的颜色变化最为明显。该材料碳链长度合适，碱度强，吸附量高达1.32 mol mol−1。在1,4-苯醌溶液中浸泡30 s后，PANNPF迅速由黄色变为深棕色。胺与1,4-苯醌之间的相互作用快速，使得该方法可用于实时监测。此外，PANNPF在宽pH范围（3-10）的水中检测1,4-苯醌非常有效，检测限低至0.5 ppm。即使在低温（0℃）下，PANNPF也能保持其灵敏度和稳定的颜色变化，并且在实际应用中离子和化合物的存在不会干扰其变色行为。动力学曲线和等温曲线表明，吸附过程符合Langmuir等温吸附模型和拟二级动力学模型，证明了PANNPF对1,4-苯醌的化学吸附。这些发现突出了PANNPF优越的检测能力，使其成为一种高效可靠的环境监测和水净化材料。

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
