Oct 13, 2025 by miodeya.com 22 views

Introduction

Zeolites are naturally occurring minerals that have a three-dimensional framework structure with a connected cavity and channel. This unique structure provides a very large surface area, making zeolites effective adsorbent materials. Another advantage of zeolites is their negative charge, which allows them to interact with surfactant compounds such as cethyltrimethylammonium-bromide (CTABR). This study aims to produce natural zeolite modifications using CTABR and compare the ability of natural zeolite adsorption in absorbing phenols using activated zeolite and zeolite that have been modified with CTABR.

Background of Zeolites and CTABR

Zeolites are aluminosilicate minerals that have been widely used in various applications, including catalysis, adsorption, and ion exchange. Their unique structure and properties make them effective adsorbent materials for removing impurities and pollutants from water and air. CTABR, on the other hand, is a surfactant compound that has been widely used in various applications, including cleaning products, personal care products, and pharmaceuticals. The interaction between zeolites and CTABR has been studied extensively, and it has been found that CTABR can modify the surface properties of zeolites, making them more effective adsorbent materials.

Research Methodology

The research process begins with zeolite activation, which aims to improve its performance as an adsorbent. The activation process involves heating the zeolite at a high temperature to remove impurities and improve its surface area. After activation, the zeolite is modified with CTABR to enhance its adsorption capacity. The adsorption test is carried out to evaluate the effectiveness of CTABR modified zeolite in absorbing phenol solutions. The main parameters measured in this study include activation temperature, adsorption time, and adsorbate concentration.

Results and Discussion

The results showed that zeolite that had been modified with CTABR reached the maximum adsorption capacity at 80 ppm concentration and a contact time of 120 minutes, with an adsorption capacity of 3.424 g/mg. The adsorption process of the phenol solution shows the tendency to increase with the increase in adsorbate concentration and contact time, until it reaches the saturation point. Characteristics of Natural Zeolite and Isotherm of Natural Zeolite Adsorption functions as a parameter to assess the effectiveness of the adsorption of phenol solutions in this study.

Further analysis shows that the adsorption process follows the Freundlich model, with a correlation coefficient of 0.998. This model indicates that the maximum capacity of the adsorption (N) is 1,3693 mg/g, while the Freundlich constant is 4,3102 L/mg. These values indicate that the adsorption process is physical and forms a multilayer layer. If the N value is greater than 1, the adsorption capacity will increase with the active side of the zeolite.

Environmental Implications

In the environmental context, this research has significant implications. Phenol is a toxic compound that is often found in industrial waste, and its presence in water can endanger the health of humans and ecosystems. By modifying zeolite using CTABR, this study shows an effective way to improve the ability of zeolite in absorbing harmful compounds. This method not only offers solutions for waste treatment but also reduces the impact of environmental pollution.

Conclusion

Overall, the modification of natural zeolites with CTABR shows great potential as an innovative strategy in waste treatment, especially in absorbing toxic substances such as phenols. By continuing to develop this method, it is hoped that a more efficient and environmentally friendly solution can be found for future pollution problems.
