The Feasibility of Rice Husk to Remove Minerals From Water by Adsorption and Avail From Wastes
Authors: ,
Abstract: This investigation is concerned to study the susceptibility of Iraqi Rice Husk (IRH) on the removal of five minerals pollutants which were (B, Ba, Be, Bi, and Se) ions from simulated synthetic aqueous solution (SSAS) using different design parameters by adsorption process. Results show that the removal efficiency of minerals (B, Ba, Be, Bi, and Se) from (SSAS) was decreased with increasing of initial concentration, flow rate and pH for some minerals which were (B, and Bi) while it was increased with increasing absorbance material bed height, feeding temperature and pH for rest minerals (Ba, Be and Se). Statistical model is achieved to obtain an expression relates overall operating parameters with the removal efficiency for each mineral ions used in this treatise in a general equation. The samples of (IRH) remaining after using it in adsorption of these seven metals above from (SSAS) were predestined to investigate the utilization of it in different methods. One of these methods was preparing of promoted type Y-zeolite catalyst and compared these type prepared with normally type Y-zeolite catalyst prepared from (IRH) alone in the process of n-heptane isomerization under different temperatures. Another method was study the using of these (IRH) as a rodenticide directly without any pretreatment. The results show that the promoted type Y-zeolite catalyst by (B, Ba, Be, Bi, and Se) ions give higher conversion and better selectivity of n-heptane isomerization than normally type Y-zeolite catalyst and the (IRH) adsorb (B, Ba, Be, Bi, and Se) from (SSAS) showed a good behaviour as rodenticide. By this way we can possess different benefits which are: remove the five mineral ions contaminated the water, get rid of agricultural waste (IRH), in the same time, produce light and more benefit hydrocarbons from n-heptane isomerization using a type Y-zeolite catalyst synthesis from remaining (IRH) and prepare an active rodenticide. So, it can discard more toxic waste in a coast and eco-friendly method.
