Utilization of silica extracted from soybean hulls for chromatographic studies of catechol amines

Cultivation of soybean is extensively done in Malwa region of Madhya Pradesh nearly 80% of total soybean produced in India. And it is classified source of oil and protein. Its seed are dehulled and the hulls being by- product of these industries, therefore a preliminary attempt was made to utilized this waste for extraction of silica from it by sodium carbonate fusion followed by hydrolysis. The purity and percentage of extracted silica was estimated by conventional HF- method(hydro floric) and characterization is done by various physio-chemical techniques viz. IR, X-ray diffraction, TG pattern SEM, .etc. The result shows absence of extraneous impurities in significant amount. The silica so obtained was used as adsorbent for chromatography study of Cathecol amines to explore its practical utility. Good results were obtained.
