Adsorption of Metalworking Fluids in CSTR Reactor by Modified Sugarcane Bagasse with Aluminium Sulphate as Adsorbent

Abstract

Metalworking fluids (MWFs) are widely used in the metal forming industrials. It was used for reducing of the friction and cooling of the mechanical processes. In this research, the modified sugarcane bagasse (MSB) with aluminium sulphate (Al2(SO4)3) was used as an adsorbent for removal of the metalworking fluid in Continuous Stirred Tank Reactor (CSTR). The point of zero charge of sugarcane bagasse and modified sugarcane bagasse were pH 6.1 and 3.7, respectively. The effect of initial concentration of metalworking fluid was studied. When used the reactor 3 L and flow rate at 0.055 L/min, the % removals of MWF at initial concentration 6,480-41,513 g/m3 were 98.0-56.7%, respectively. The significant uptake of metalworking fluid was demonstrated by FT-IR spectroscopy.
