Energy Efficient and Fast Process of Silica Separation from Rice Stubble

Silica is one of the significant inorganic compounds which is present in various plants in varying amount which makes the plant forage unusable as fodder for animal consumption as well as causes serious diseases such as silicosis, lung cancer and chronic obstructive pulmonary disease (COPD). Along with this, silica is not biodegradable which leads to difficulties in degrading plant fodder as a whole. So in order to treat plant waste, Sodium Hydroxide (NaOH) under the presence of microwaves (frequency – 2.45GHz), can be used to provide a non-thermal source of energy. The motive behind using microwave is to catalyze the endothermal reaction. The reaction process can be tweaked by manipulating Electric and Magnetic field ratio (E:H). During the experiment, we found out that by decreasing the ratio (increasing the magnetic field strength), the kinetics of the chemical reaction increases which fasten the process. Thus Silica can be precipitated out in the form of Sodium Silicate (Na2SiO3).
