Adsorption of Sulfate in Aqueous Solutions by Cheap Plant Adsorbents

摘要

In this study, the possibility of sulphate adsorption from a synthetic solution containing sodium sulphate was investigated using corn and wheat straw. The initial results showed that modified corn had the best absorbance among the samples. The temperature, mixing time, adsorbent amount and also the amount of sulfate ions in the solution as effective parameters in the adsorption process were investigated. It was observed that with increasing temperature, the adsorption rate decreases due to the thermostability of the reaction. Also, increasing the time before reaching a saturation state, the absorption capacity is increased.
