“…Table 4 shows the amount of the Qmax and K parameters, and the value of the linear regression, R 2 . Adsorption isotherm models were recommended to determine adsorption capacity, as stated by several studies [30,31,32]. In this experiment, the Langmuir equation model defines the tendency of adsorption data with values of > 0.70 for R 2 , as shown in Table 4.…”

The adsorption capacity of four clay samples (Boyolali-BYL, Sleman-SLM, Gunungkidul-GK, and Pacitan-PCT) from Java, Indonesia, for copper (Cu) lead (Pb), zinc (Zn) and cadmium (Cd) solution was investigated by using batch equilibrium test. The adsorption data were presented using an isotherm curve, and adjusted to the Langmuir equation model, which produced the maximum adsorption capacity of the clay samples. The physical, chemical, and mineralogical analysis showed that the BYL and PCT samples have higher montmorillonite content, cation exchange capacity (CEC), and specific surface area (SSA) compared to SLM and GK clay samples. The batch equilibrium test revealed that the clay samples with higher montmorillonite content produced higher heavy metal adsorption capacity due to the higher cation exchange capacity (CEC), and specific surface area (SSA). The batch equilibrium test also show that the adsorption order for the metals cations followed the selectivity order Cu2+ > Pb2+ > Zn2+ >Cd2+. The Langmuir model resulted in the adsorption processes, offering maximum adsorption capacities from 196.08 to 769.23 mg/g for Cu, 217.39 to 416.67 mg/g for Pb, 106.38 to 114.94 mg/g for Zn and 104.17 to 113.24 mg/g for Cd of four clay samples studied. The highest adsorption capacity was achieved for the BYL sample. The lowest was the GK sample, in which the order of the maximum adsorption capacity of clay samples was BYL > PCT > SLM > GK sample. This research indicated that the proportion of montmorillonite content in the clay samples affected the maximum adsorption capacity of the heavy metal in the solution.

“…Furthermore, the pretreatment of natural zeolites with NaCl has been found significant for increasing the adsorption capacity of heavy metal removal from wastewater [ 23 , 24 ]. Additionally, recent studies demonstrate the potential for cadmium adsorption on natural zeolites from water, with removal efficiency between 70 and 99 % indicating that a large amount of cadmium concentration has been decreased after adsorption on zeolites [ 25 , 26 ]. The adsorption of heavy metals in natural zeolites can be facilitated through many mechanisms, including anion exchange, electrostatic attraction, intrapore diffusion, complexation, chemical reduction, etc.…”

An experiment of the immobilization of heavy metals Pb, Cu, Zn, and Cd in contaminated soil by using the natural zeolite was performed in the laboratory. The natural zeolite was obtained from Gunungkidul, Yogyakarta, Indonesia. Artificially contaminated levels on 100, 300 and 500 mg/kg were prepared and then mixed with three different dosages of 5%, 10% and 20% of the natural zeolite. The result revealed that the addition of natural zeolite effect on reducing the heavy metal in the contaminated soil. The addition 5% dosage of the natural zeolite was sufficient to reduce the concentration of Pb, Cu and Zn from 500 mg/kg to the maximum permissible of concentration level. Finally, the natural zeolite immobilized the heavy metals in the contaminated soil by following in order: Pb2+>Cu2+>Zn2+>Cd2+.
