This research employed untreated aluminum dross obtained from auto parts manufacturing waste as an adsorbent to meet the sustainable goals of waste utilization in readily available, inexpensive, and environmentally friendly materials to treat cutting oil wastewater in auto parts manufacturing. Aluminum dross, categorized as white dross with 37.13% aluminum and 7.77% silicon, is a source of silicon-and aluminum-containing wastes. Process optimization was conducted using a central composite rotary design (CCRD) coupled with response surface methodology (RSM). The results indicated that the adsorption of aluminum dross at optimum conditions was 15 g adsorbed from 1% v/v cutting oil wastewater at pH 2 in 60 minutes, achieving the removal efficiency at 93.30% of chemical oxygen demand (COD), 88.33% of turbidity, and only 40.47% of total organic carbon (TOC). The second-order equation demonstrated coefficients of determination (R 2 ) and adjusted R 2 values of 0.9738 and 0.9345, respectively, for COD removal. The COD adsorbed on aluminum dross could be adequately explained using the pseudo -secondorder kinetic and Langmuir models. Aluminum dross adsorption for cutting oil treatment has a low operating cost of 0.5398 USD/m 3 .

“…Aluminum dross is the molten slag solid waste that results from the production and recycling process of electrolytic aluminum, cast aluminum and other aluminum industries [1] [4] [5]. To date, the treatment of aluminum dross waste mainly consists of accumulation in landfills, which not only seriously pollutes the environment, but is also a waste of aluminum resources [6] [7] [8] [9].…”

In the aluminum industry, secondary aluminum dross (SAD) is an inevitable solid residue, which usually contains 30-70 wt% Al 2 O 3. In this work, Al(OH) 3 was extracted from SAD through acid-leaching and alkali purification process. The as-obtained Al(OH) 3 precipitation then was calcinated to synthesize porous γ-Al 2 O 3 assisting by an agricultural waste biomass-corn straw as biotemplate. Effects of H 2 SO 4 concentration, reaction temperature and time on the recovery of SAD were investigated. Furthermore, the dependence of calcination temperature on specific surface area, pore volume and content of porous γ-Al 2 O 3 was analyzed. X-ray diffraction (XRD) and X-ray fluorescence (XRF) were used to inspect the phase compositions and their contents, respectively. Scanning electron microscopy (SEM) was employed to analyze the morphologies of the sintered porous γ-Al 2 O 3. It was found that the highest recycle rate of aluminum from SAD was obtained under optimum conditions of 80˚C, acid concentration of 1.6 mol/l, and reaction time of 5 h by acid process. The porous γ-Al 2 O 3 with specific surface area, 261.22 m 2 /g and average pore diameter, 52.64 nm, was obtained under calcination at 850˚C through mixing the as-obtained Al(OH) 3 precipitation and corn straw.
