OPTIMIZATION OF SYNTHESIS PARAMETERS FOR LEAD OXIDE NANOPARTICLES USING RESPONSE SURFACE METHODOLOGY

Abstract

Nano-sized lead oxide has useful applications that can be used in industry. In this study, the synthesis parameters were optimized using response surface methodology and ANOVA study was also carried out. Reaction temperature, sodium hydroxide and lead (II) acetate concentration were studied as the factors and the particle size was selected as the response variable. The modification was lead to increase the adequate precision of the model. Close results between R² (correlation coefficient) and R²_adj showed the accuracy of the model. The optimum results of the study were found 14.89 M NaOH concentration, 0.87 M Pb(II)Ac and reaction temperature of 88.56 °C. The particle size of lead II oxide was found to be 19.75 nm under optimum parameters.

Yüzey Cevap Metodolojisi Kullanilarak Kurşun Oksit Nanoparçaciklarinin Sentez Parametrelerinin Optimizasyonu

Öz

Nano boyutlu kurşun oksit, endüstride kullanılabilecek faydalı uygulamalara sahiptir. Bu çalışmada, sentez parametreleri cevap yüzey metodolojisi kullanılarak optimize edilmiş ve ANOVA çalışması da yapılmıştır. Sentez parametreleri olarak reaksiyon sıcaklığı, sodyum hidroksit ve kurşun (II) asetat konsantrasyonu incelenmiştir ve parçacık boyutu cevap değişkeni olarak seçilmiştir. Optimizasyon sonucunda modelin hassasiyeti artmıştır. R² (korelasyon katsayısı) ile R²_adj arasındaki yakın sonuç, modelin doğruluğunu göstermiştir.  Çalışmanın sonucunda, 14.89 M NaOH konsantrasyonu, 0.87 M Pb (II)Ac konsantrasyonu ve 88.56 ° C reaksiyon sıcaklığı optimum sentez koşulları olarak belirlenmiştir. Kurşun (II) oksidin parçacık büyüklüğü, optimum parametreler altında 19.75 nm olarak bulunmuştur.
