The environmental contamination caused by pharmaceutical and personal care products (PPCPs) is a global issue. Although the reported quantities of PPCPs are typically modest, several PPCPs with various chemical compositions have been found in soil, water, and aquatic habitats. The majority of these bacteria can survive in the environment for long periods of time, causing risks to human health, biota, and other important environmental factors. PPCP-contaminated sites have been cleaned via a variety of approaches, including bioremediation, ozonation, electrochemical separation, and physicochemical treatments such as coagulation, volatilization, sorption, and sedimentation. An extensive review of PPCP sorptive removal methods and interaction mechanisms is given in this chapter. Acid-digested carbon from waste leather can be used as a low-cost alternative to traditional scientific methods for removing pharmaceutical drug contaminants. The garbage is collected from leather-related businesses and from India's domestic waste leather industry. The adsorbent was then dried, ground into a powder, sieved, and cleaned until the particle size reached 63 µm. The adsorbent was introduced to HCl in a 0.1 M solution for 24 hours. Afterward, the mixture was filtered, cleaned with double distilled water, and dried once more. It is important to consider several factors, such as temperature, concentration, pH, contact time, amount, and size. This method can reduce the cost of treating wastewater as well as the harm it causes to the environment.
