However, in Serbia, the full benefits of the use of mineral absorbents can only be seen with the readiness of customers to purchase poultry meat products according to their quality. Natural Materials as Low Cost Adsorbents for Water Treatment. Examples of adsorbents include clays, chars, alumina, and silicates. Academia.edu no longer supports Internet Explorer. is adsorption, which has the advantages of being fast, cheap, and universal. Some of the carbon materials such as … There are number of water purification techniques but the adsorption is one of the most simplest, effective and economical method for wastewater purification. Use of waste materials as low-cost adsorbents is attractive due to their contribution in the reduction of costs for waste disposal, therefore contributing to environmental protection.
