“…ACUTLaqE composite varying in weight (0.2, 0.4, 1, 2, 4, 8, 12, 16, and 20 g/L), contact time (5,10,15,20,25,30, and 35 min), and initial concentration (40, 50, 60, 70, 80, and 90 mg/L) at room temperature (T=25±2 °C) were studied through the batch adsorption process. After that, the flasks were withdrawn, the mixtures were filtered through filters (Wattman 102), and an AAS was used to quantify Pb 2+ content [30,31,[52][53][54][55]. R and qe (mg/g) are the adsorption rate and equilibrium adsorption uptake of Pb 2+ respectively, calculated using the following equations ( 1) and (2).…”
