in the water is dangerous. Lindane stays in the environment for a long time, where it can get into the cells of fish and, consequently, humans. Moreover, the pesticide may lessen the motility and concentration of sperm, alter the specific activity of a testicular marker enzyme, and cause oxidative stress in humans [6]. Additionally, it may cause testicular dysgenesis syndrome, alter serum testosterone levels, and reduce the amount of testosterone in the body. The presence of a significant number of chlorine atoms within the molecule of lindane causes it to be regarded as a substance that can cause disruptions to the body's endocrine system [7]. This is because lindane is a highly toxic substance. Because of its high persistence level and ability to bioaccumulate and travel long distances, lindane is classified as a persistent organic pollutant, or POP [7]. As a result, there has been a rise in research focused on Lindane removal from contaminated water. The adsorptive removal method has been given a lot of preference in recent years because, compared to other ways, it has a very high efficiency at a low cost [8]. Adsorption, however, is controlled by several process variables, including temperature, pH of the medium, and contact time and concentration between the adsorbate and adsorbent. The impact of these parameters on the adsorption process is typically evaluated using batch adsorption studies that use the traditional OVAT approach [9]. This approach usually consumes time and resources and does not account for multivariate interactions among the variables [10]. Adsorption studies based on OVATs have challenges when examining multivariate/inter-parametric interactions between the physico-chemical parameters that synergize contaminant uptake [9]. Multivariate calibration and analysis using chemometric prediction techniques like ANN provide crucial insight into the impact of normative variability on the method in question [11]. The ANN is a tool that has recently become a powerful method for addressing issues prevalent in the real world and has garnered a great deal of attention due to its applications in various fields [12; 13; 14]. For example, it has been utilized in water treatment and offers solutions that are both practical and effective for the problem of water pollution [12]. However, the comparison of ANN and SR performances for the adsorption applications is scanty in the literature. In this work, however, we want to look at the model that will suggest optimum parameters that will give us the highest removal efficiency without rigorous experiments.
