Silicon is the second most abundant element in the earths crust, second only to oxygen. It is naturally found as fairly pure silicon dioxide and as silicates. The silicon dioxide is found as huge deposits of quartzite or quartz sand. Moreover, many rocks contain quartz crystals. Therefore, it
Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel USGS, 2013b. Thus, the worlds use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.
The sand obtained from optimum concentration and volume of HCl solution was then reacted with different amounts of NaOH s, and heated until a wet mixture was obtained. As a reference the best extraction conditions were applied to a natural zeolite sample. All OSA analyses were done in triplicates with spectrophotometric method.

Jan 14, 2010 Research in plant molecular biology involves DNA purification on a daily basis. Although different commercial kits enable convenient extraction of high-quality DNA from E. coli cells, PCR and agarose gel samples as well as plant tissues, each kit is designed for a particular type of DNA extraction work, and the cost of purchasing these kits over a long run can be considerable.
Silica is a form of silicon dioxide, which forms when silicon comes into contact with oxygen. Its actually the second most abundant nutrient found in the Earths crust, and thus its highly concentrated in many soils, which in turn makes it a major component of plant tissues.
