Ultrasonik Ses Dalgası Ortamında Polielektrolit Varlığında Kalsiyum Karbonat Sentezi, Karakterizasyonu ve Deneysel Tasarım

Öz

Bu çalışmada ultrasonik ses dalgası (USD) uygulanarak suda çözünebilir polielektrolit olan polivinilsülfonik asit (PVS) varlığında kalsiyum karbonat (CaCO₃) sentezlenmiştir. Sentezlenen CaCO₃ kristalleri XRD, taramaları elektron mikroskobu (SEM), parçacık boyutu analizi ve termogravimetrik analiz (TGA ve DTA) ile karakterize edilmiştir. 2^k Faktöriyel Tasarım uygulanarak, sonikatör genliğinin, polimer konsantrasyonunun ve USD uygulama zamanının elde edilen kalsiyum karbonat kristallerinin boyutuna etkisi incelenmiştir.  Deneysel tasarım iki seviyede gerçekleştirilmiştir. Seçilen tüm proses parametrelerinin PVS varlığında elde edilen kalsiyum karbonatın parçacık boyutunda çok etkili olduğu görülmüştür.

The Synthesize of Calcium Carbonate Its Characterization and Experimental Design in an Ultrasonic Sound Wave Environment and in the Presence of Polyelectrolyte

Abstract

In this study, calcium carbonate (CaCO₃) was synthesized by means of ultrasonic irradiation process in the presence of the water-soluble polyelectrolyte Poly(Vinyl Sulfonic Acid) (PVS). Synthesized CaCO₃ crystals were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), particle size and thermal analysis (TGA-DTA). The effects of the amplitude of sonicator, polymer concentration and the application time of ultrasound on the obtained CaCO₃ with respect to particle size of final product was investigated by applying the 2^k Factorial design. The experimental design was studied at two levels. All the selected process parameters were found to be very effective on the particle size of calcium carbonate obtained in the presence of PVS.
