Abstract

This study investigated the adsorption capacity of rice husk and seashell compounds. Particles were classified in five different sizes of 841, 400, 177, 125 and 74 μm which based on ASTM sieves. Sodium chloride solution was prepared in different concentration of 25, 50, 100, 200, 300, 500, 750, 1000, 3000, 5000, 7000 and 10000 ppm. The effects of the sizes, dosage, contact time, rate of mixing with duration of 10, 15, 25, 35, 45, 60 and 120 minutes for the salt removal done with batch experiments in 25oC. in this method the sodium chloride solution with certain amounts of adsorbent put on a shaker device with constant speed of 200 rpm and were mixed at intervals of 10, 15, 25, 35, 45, 60 and 120 minutes. Then the samples in centrifuged with 10000 rpm in 10 minute and the upper solution used for chloride titration. The effects of different amount of absorbent on salt absorbance showed that for all samples the highest absorbance is related to the range of 2 gram. Due to increasing of absorbents quantity from 0.5 to 2 gr, the absorbance percentage of rice husk and sea shell from 51 to 58 and 27 to 42 respectively. Among the used sizes of particles the most efficiency was related to the size of 74 mm in salt absorption. The optimum time of used samples was identified as 25 and 10 min for rice husk and sea shell respectively. Based on isotherm model, rice husk followed langmouir model, while seashell followed Freundlich.
