Description
The removal of prothiofos from chamomile oil has been investigated as a function of adsorbent type, adsorbent concentration, time and temperature. Therefore, 14C-prothiofos was prepared in our laboratory. Low cost adsorbent such as agricultural wastes (Rice bran, rice husk, and watermelon peels), industrial by-products (sawdust-bagasse) in addition to calcium oxide as a chemical adsorbent were used. It was found that, the best adsorbent concentration for the insecticide removal is 0.016 g adsorbent/g oil. The maximum removal of prothiofos from chamomile oil was 87%, 90% by using calcium oxide and watermelon peels, respectively at 30 degree C for 2 hours. Saw dust, bagasse and rice bran proved to be better for the insecticide removal at 40 degree C
