Öz

Günümüzün en önemli teknolojilerinden biri olan nanoteknolojideki gelişmeler her alanda olduğu gibi çevre alanında da kullanım şekillerini arttırmaya başlamıştır. Bu teknoloji düşük maliyetli, çevre dostu alternatif malzeme üretiminde kullanılabildiği gibi aynı zamanda hem mevcut kaynaklarımızı korumada ve kirleticilerin tutulması, arıtımında da kullanılabilmektedir. Bu bağlamda bu çalışma nanopartiküllerin çevre mühendisliğinde kullanım alanları ve temel laboratuvar malzemeleri ile gümüş nanopartikül sentezi hakkında hazırlanmıştır. Çalışmanın sentez bölümünde elde edilen nano gümüş çözeltisi, sodyum borhidrür (NaBH₄) kullanılarak gümüş tuzunun (AgNO₃) indirgenmesi ile kimyasal yöntem ile oluşturulmuştur. Oluşturulan ürün Taramalı Elektron Mikroskobu (SEM) ve UV-VIS spektrometre ile karakterize edilmiş ve boyut analizi gerçekleştirilmiştir. Elde edilen nanopartikül boyutlarının yaklaşık 70 nm ~ 77 nm arasında olduğu gözlemlenmiştir. Ayrıca gümüş nano partiküllerin adsorpsiyon seviyesinin 350 ~450 nm aralığında ve 396,016 nm olduğu bulunmuştur.

Use of nanoparticles in Environmental Engineering and synthesis of silver nanoparticles (AgNPs) with basic laboratory materials

Abstract

As one of the most important technologies of today, nano technological developments have begun to increase the usage patterns in the environment. This technology can be used in the production of low-cost, environmentally friendly alternative materials, as well as in the protection of our existing resources and the Keeping of contaminants. In this study, it has been shown where nanoparticles are used in the field of environmental engineering and how to synthesize and synthesize silver nanoparticle synthesis by chemical methods by using simple equipments in laboratory conditions and how they are shaped and shaped. The nano silver solution was formed by reduction of the silver salt (AgNO₃) using sodium borohydride (NaBH₄). The product was characterized by Scanning Electron Microscope (SEM) and UV-VIS spectrometer and size analysis was performed. It was observed that the nanoparticle size obtained was approximately 70 Nm ~ 77 Nm. In addition, the adsorption level of silver nano particles were measured between 350 ~ 450 Nm. It was found to be approximatel 396,016 Nm.
