Abstract

This study aimed to analyze the adsorption ability of black sand in the metal ions adsorb cadmium (Cd2+) with a concentration of 70 ppm to a solution with a pH of 4,5. The black sand is used is 40 mesh. This research was conducted by batch adsorption system naturally and adsorption kinetics modeling. Kinetics of adsorption reached equilibrium at time t = 120 minutes with the percentage concentration of adsorbed Cd2+ 18,5%. In the adsorption kinetics modeling correlation coefficient is almost the same between the equations of first order and second order in the amount of 0.98 and 0.99. The result indicated that the type of interaction Cd2+ ions on the surface of black sands occur in chemistry and physics. The adsorption kinetics of diffusion modeling of internal and external diffusion of the correlation coefficient of 0,85 and 0,71. From this data it can be seen that in this study is modeling kinetic internal diffusion trend that shows adsorbent particles are inter sand surface area that experienced internal inter-particle pore diffusion.

Abstract

Indonesia is recognized as the world's leading producer of palm oil (Elaeis guineensis Jacq.), which contributes to a substantial accumulation of oil palm biomass waste. Among these, oil palm fronds present a promising potential as low-cost and eco-friendly adsorbent materials. Concurrently, the repeated use of cooking oil generates used cooking oil, a waste product that poses significant health risks due to the accumulation of harmful compounds. This study explores the application of oil palm frond-based adsorbents for the purification of used cooking oil through an adsorption mechanism. Experimental results revealed that the optimal adsorbent performance was achieved using 4.5 grams of adsorbent with a particle size of 100 mesh, which successfully reduced the turbidity of used cooking oil to 28.5 NTU, with a total adsorbed turbidity value of 95.5 NTU. Kinetic modeling indicated that the adsorption process followed a pseudo-second-order model, supported by a high correlation coefficient (R² = 0.9983), suggesting that the adsorption mechanism is dominated by chemisorption involving chemical interactions between the adsorbent surface and the contaminants in the oil.

Abstract

Indonesia is the second largest producer of palm oil in the world today after Malaysia. Since 2003, the amount of palm oil production in Indonesia has reached approximately 9.9 million tons per year. According to (BPS 2021), the area of oil palm land in North Sumatra reached 442 072.76 hectares. This research will purify used cooking oil using natural adsorbents by utilizing palm frond waste. Palm fronds are chopped into powder, then sifted with sizes of 50, 70 and 100 mesh after which they are weighed with weights of 1.5, 3 and 4.5 grams. Oil palm frond adsorbents with mass variations of 4.5 grams have the greatest adsorption power in reducing used cooking oil and the best adsorption kinetics based on the correlation coefficient is the pseudo second order equation.

Abstract

The statistics center in 2021 stated that North Sumatra is the second largest palm oil-producing province in Indonesia with a plantation area of 1,373.30 Ha. The use of cooking oil in Indonesia in 2021 was 18.4 million tons and increased by 6% from the previous year. This research utilizes palm fronds for the manufacture of adsorbents in cooking oil refining. The method used is carbonization with the help of pyrolysis. The carbon is chopped into powder and divided by variations of 1.5, 3, and 4.5 grams. Each gram is stirred using a shaker with speed variations of 50, 70, and 100 rpm. Turbidity is tested using a turbidimeter once every 20 minutes for 180 minutes. The results of the analysis showed that the best adsorbent weight in reducing used cooking oil was 4.5 grams with a turbidity level of 15.5 NTU and stirring of 100 rpm.
