Interface adsorption of gases and liquid on a clean solid surface could be due to the physical or chemical adsorption. In this study, the activated carbon was prepared from sugar cane husk (powder and granular form) using phosphoric acid (H3PO4) as activating agent. Sample was activated at 500°C for two hours in the furnace and washed using vacuum method. Besides, surface area of activated carbon was defined using Single Point Brunauer-Emmett-Teller (BET) Nitrogen Gas. The physico-chemical characteristics of the prepared activated carbon were characterized by Fourier-Transformed Infrared Spectroscopy (FTIR), gravimetric method, and Field Emission Scanning Electron Microscopy (FESEM). The adsorption study by surfactants, namely CTAB (cationic) and TX-100 (non-ionic) were investigated. The experimental results showed that a good activated carbon was prepared from sugar cane husk granular (SCH-G) gave the highest BET surface area of 860.18 m2/g and the adsorption capacity of SCH-G activated carbon at 25°C using TX-100 (205.81 mg g-1) was greater compared to the CTAB (108.20 mg g-1). This study has shown that the sugar cane husk was a good activated carbon and has potential to be used as adsorbent for the removal of surfactants from aqueous solutions.

In this study the Sugar cane bagasse ash (SCBA) was characterized for chemical composition, morphological and mineralogical properties. From XRF analysis it was found that the SCBA has SiO2, Al2O3, Fe2O3 and CaO content of 67.25%, 6.37%, 4.21% and 13% respectively and it has a very low LOI value of 0.34% and can be classified as Class F ASTM pozzolan according to ASTM C 618-2009. SCBA can be used as a pozzolanic material after grinding to less than 45 Micron. Based on the properties obtained from the characterization in this study it can be concluded that, utilization of SCBA in concrete will positively affect hardened concrete properties due to pozzolanic reaction, cementing properties and filling effect of SCBA. Moreover it will minimize the negative impacts associated with SCBA disposal.
