Adsorption process has been proven to be one of the best water treatment technologies around the world. The present study attempts to use waste material (eggshell) as adsorbent for salicylic acid removal and compare its activity with activated carbon. Many variables were studied to indicate their influence on removal efficiency. They have been included pH of solution were (2-11), salicylic acid concentration (10-50ppm) and adsorbent concentration (10g/l - 25 g/l) for eggshell while for activated carbon (1g/l -5g/l). From the experimental results, there were noticed that the percentage removal increased with increasing adsorbent concentration, acidic solution while decreased with increasing salicylic acid concentration. Also, the results indicated that eggshell gave lower removal compared with activated carbon. Therefore the best conditions are pH solution was 2, salicylic acid concentration 10ppm, activated carbon amount 5g/l while for eggshell 25g/l that achieved percent removal reached 97 % and 24% for activated carbon and eggshell respectively.
