  Green synthesis of silver nanoparticles using Terminalia cuneata and its catalytic action in reduction of direct yellow-12 dye

  摘要：

  Facile green synthesis of silver nanoparticles (AgNPs) using aqueous bark extract of Terminalia cuneata has been reported in this article. The effects of concentration of the extract, reaction time and pH were studied by UV-Vis spectroscopy. Appearance of yellow color with lambda(max) around similar to 420 nm suggested the formation of AgNPs. The stable AgNPs were further characterized by Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), dynamic light scattering (DLS) with zeta potential and high resolution transmission electron microscopy (HR-TEM) with energy dispersive X-ray spectroscopy (EDS) analysis. The synthesized AgNPs were in the size range of 25-50 nm with a distorted spherical shape identified from HR-TEM analysis. The catalytic activity of AgNPs on the reduction of direct yellow-12 using NaBH4 was analyzed using a UV-Vis spectrophotometer. This study showed the efficacy of biogenic AgNPs in catalyzing the reduction of direct yellow-12. (C) 2016 Elsevier B.V. All rights reserved.

  A series of new high light fastness, hot pressing fastness optical brighteners was efficiently synthesized by a three-step approach involving the successive replacement of the three chloro groups of 2,4,6-trichloro-1,3,5-triazine under different conditions of temperature and pH. Thus, 2,4,6-trichloro-1,3,5-triazine was treated with different anilines and the resulting dichlorotriazinyl intermediates (3a-I) were further condensed with 4,4-diaminostilbene-2,2′-disulfonic acid to afford bis-monochlorotriazine (5a-I) followed by nucleophilic substitution with ethanolamine to furnish the final hybrid brighteners (7a-I). All of the newly synthesized compounds were characterized by Fourier-Transform Infrared (FT-IR), UV-visible absorption, NMR spectroscopy and the elemental analyses. The synthesized optical brighteners were also assessed for their efficacy as fluorescent brightening agents.

  在不同的温度和 pH 值条件下，通过三步法连续取代 2,4,6-三氯-1,3,5-三嗪的三个氯基，高效合成了一系列新型高耐光性、热压牢度光学增白剂。因此，2,4,6-三氯-1,3,5-三嗪先用不同的苯胺处理，得到的二氯三嗪中间体（3a-I）再与 4,4-二氨基二苯乙烯-2,2′-二磺酸缩合，得到双一氯三嗪（5a-I），然后用乙醇胺进行亲核取代，得到最终的混合增白剂（7a-I）。所有新合成的化合物都通过傅立叶变换红外光谱（FT-IR）、紫外-可见吸收光谱、核磁共振光谱和元素分析进行了表征。还评估了合成的光学增白剂作为荧光增白剂的功效。
