Abstract
The adsorbent is a solid substance that can absorb certain components from the liquid phase. Most of the adsorbents are porous materials and the adsorption process takes place, especially in the porous wall or certain location inside that particle. The main objective of this research is to study the influence of the adsorbent’s surface area based on shape variation from corn stalk with adsorption ability to reduce the water river’s turbidity, the influence of time with adsorption capacity in reducing river water’s turbidity, the influence of adsorbent with water river and adsorption capacity, and defining adsorption kinetics from corn stalks. The shape of corn stalks that have been used such as spherical, half of spherical shape, and quarter of spherical shape. The volume of the sample is 250 mL. The measurement time is 300 minutes. The mass variations that have been used are 10 g, 15 g, and 20 g. The variation of sample takeover in the morning, afternoon, and evening. The measurement of adsorbent adsorption capacity in term of decreasing the turbidity of Babura River’s water is done by inputting the adsorbent into the sample, then the measurement of the water’s turbidity proceed by using a turbidity meter. The analysis result for the influence of the adsorbent’s surface area in decreasing Babura River’s water in the shape’s variation from spherical, half of spherical shape, and quarter of spherical shape is obtained in quarter of spherical shape. The highest amount of adsorbent in decreasing the turbidity of Babura River’s water is 20 g. Adsorption kinetics that has been used in the measurement of decreasing Babura River’s water turbidity is second order kinetics
