摘要

在过去的几十年里,地表水、河底水流、地下水和冷冻水显示出由于染料和纺织相关工业中含有化学废物的染料而产生的污染物的存在。其中一种亚甲基蓝染料被用于纸张染色、临时染发、棉花和羊毛染色,其废水被亚甲基蓝染料污染。废水中染料的去除具有重要意义,因为它对环境危害严重,会对人体健康造成严重损害。因此,有必要解决染料污染造成的影响。近年来,纳米颗粒被报道用于工业废水中的染料去除。因此,使用纳米颗粒作为吸附剂的污水处理提供了更大的表面积,更少的时间消耗,环保,简单和具有成本效益的过程。在本研究中,对纳米银在水溶液中去除亚甲基蓝染料的潜力进行了探索。为此,以番木瓜甲醇叶提取物为原料合成了银纳米粒子,并用光谱技术对其进行了表征。采用间歇平衡法进行吸附研究。为获得最佳吸附条件,研究了染料初始浓度和接触时间对染料去除率的影响。

Carica papaya Leaves Extract for Biosynthesis of Nanoparticles and Their Application
In the last few decades’ surface water, under river flow, groundwater and frozen water shows the presence of pollutant due to dyes containing chemicals waste from dyes and textile related Industries. One of the such methylene blue dye is utilized for coloring paper, temporary hair coloring, dyeing of cotton and wools, as a result its effluents is contaminated with methylene blue dye. Removal of the dyes from the effluent is of very important due to the serious environmental hazards that can result into sever health damages, particularly for human being. Therefore, there is a need to resolve the implications caused by dye pollution. Recently nanoparticles are reported for the dye removal from the industrial waste water. Therefore, effluent treatment using nanosize particles as an adsorbent provides more surface area, less time consumption, eco-friendly, easy and cost-effective process. In the present study, efforts were made to study the potential of silver nanoparticles for the removal of methylene blue dyes from aqueous solution was greatly explored. For this purpose, silver nanoparticles were synthesized using Carica papaya methanolic leaves extract and were characterized by spectral techniques. The adsorption study was conducted by batch equilibrium method. To achieve the optimum adsorption conditions, the influence of initial dye concentration and contact time on the removal efficiency of dye has been studied.
