EVALUATION OF THE ABSORPTION CAPACITY OF THE SOLID PRODUCT(CHAR) OBTAINED FROM THE WASTE TYRE RUBBER VIA CHEMICAL DEGRADATION TO REMOVE LINEAR ALKYL BENZENE SULPHONIC ACID(LABSA) FROM AQUEOUS SOLUTION

Abstract

Linear alkylbenzene sulphonates (LABSA) are highly water soluble surface active agents widely used in synthetic laundry detergent formulation and household cleaning products. Other industrial activities involve handling sulphate ion-bearing effluents found in the production of fertilizers, dyes, glass, paper, soaps, textiles, fungicides, leather and metals. Sulphate can cause various kinds of problems depending on its concentration and on the earth alkaline cation. Common examples include an altered taste of water, digestion troubles in animals and humans, soil acidification and corrosion of metals. The aim of the present study is to investigate the absorption capacity of the solid product (CHAR) obtained from the waste tyre rubber via chemical degradation by our research team to remove linear alkyl benzene sulphonic acid (LABSA) from aqueous solution, and also compare the its absorption capacity with the some commercial adsorbent's absorption capacities such as activated carbon (AC), multi-wall carbon nanotubes (MWCNTs), carbon blacks (CBs) under the same experimental conditions. The absorption capacity of (CHAR) experimental results were compared with those of (AC), (MWCNTs) and (CBs) under the same experimental conditions(LABSA concentration 100mg/L, 0.05 g/100ml adsorbent dose, contact time 40 minute, pH 8 and temperature 200C).The adsorption generally followed the order MWCNTs> CHAR = CBs > AC. This study showed that the solid product (CHAR) obtained from the waste tyre rubber via chemical degradation has a high adsorbent capacity.
