Abstract

Chromium (Cr) the most widespread metal is generally found in rocks, animals and plants, while its entrance to the environment occurs from industrial processes e.g. oxidative dyeing, steel works, tanning industries, and chemical industries etc. The study aims were Graphene oxide nanoparticles (GO-NPs) preparation and its evaluation for chromium six (Cr⁺⁶) removal from water as well as the assessment of the effect of various factors (pH, temperature, contact time etc) over Cr⁺⁶ adsorption. The target adsorbent was prepared by Modified Hummer's method and then it was treated with sodium borohydride (NaBH₄) for the synthesis of GO-NPs. The characterization was done by X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). The results indicated that highest removal (92%) was observed at pH 3 and it was concluded that the nanoparticles were efficient for Cr⁺⁶ adsorption from water. The research work was productive in estimation and optimization of different parameters for the removal of Cr⁺⁶ by GO-NPs. Further chemical modification and activation of the adsorbent is recommended.

氧化石墨烯纳米颗粒是铬污染的补救措施

铬(Cr)是分布最广的金属，通常存在于岩石、动物和植物中，而其进入环境则是通过工业过程，如氧化染色、钢铁厂、制革工业和化学工业等。研究目的是制备氧化石墨烯纳米颗粒(GO-NPs)并评价其去除水中六价铬(Cr+6)的性能，以及各种因素(pH、温度、接触时间等)对Cr+6吸附的影响。采用改进Hummer法制备目标吸附剂，然后用硼氢化钠(NaBH4)处理，合成GO-NPs。通过x射线衍射(XRD)和扫描电镜(SEM)对其进行了表征。结果表明，在pH为3时，纳米颗粒的去除率最高(92%)，表明纳米颗粒对水中的Cr+6具有较好的吸附效果。研究工作对GO-NPs去除Cr+6的不同参数进行了估计和优化。建议对吸附剂进行进一步的化学改性和活化。
