Studies on Silica Obtained from Cow Dung Ash
Abstract:
The aim of the present work is to utilize the waste material cow dung ash as a valuable material for recent research work. Silica was synthesized from cow dung ash by using sol-gel process. Characteristic parameters of cow dung ash heated to 650°C and synthesized silica were studied using different methods such as FTIR, XRD and SEM-EDS analysis. The amorphous quality of the sample was improved after the ash being calcined at 650°C. Using FTIR analysis, the presence of silanol and siloxane groups of silica was found. The amorphous nature of silica was confirmed by X-ray diffractogram. SEM studies reveal that the treated cow dung ash and silica were as flakes and in homogeneous form. The silica with higher than 99% purity with different grain size was obtained. The elemental composition of the sample was determined using EDS analysis.
