The extensive application of a pesticide, such as malathion, is a potential risk to human health as it can easily enter the food chain. An efficient and economical method for pesticide removal from the environment is necessary. In this work, we prepared a carbon material derived from biowaste (rabbit litter) for the removal of malathion from water. The adsorption capacity of carbon material derived from used litter (UL) is higher than that made from not-used litter. The maximum adsorption capacity of UL is 1.16 x10-5 mol/g for malathion
