Polycyclic aromatic hydrocarbons, also known as PAHs, are widely acknowledged to be the most common organic chemicals found in petroleum. The incomplete burning of organic materials or fossil fuels is the fundamental reason why PAHs are in the environment. Polycyclic aromatic hydrocarbons (PAHs) represent a worldwide problem because they may adversely impact human health and are poorly soluble in water. Researchers have tried various methods to remove PAHs in the environment such as photocatalytic degradation, electrokinetic remediation, advanced phytoremediation, extraction, bioremediation, chemical oxidation, adsorption and green nano remediation. Due to the remarkable adsorptive capability under lower aqueous solubility exhibited by PAH, the adsorption method has been found as one of the widely adopted methods for water decontamination. Various conventional and novel adsorbing materials function efficiently for removing PAHs from water sources. The materials used for PAH removal consist of biomass derivatives with zeolites and mesoporous silica, together with polymer nanocomposites and graphene-based materials. Environmental engineering research with material science forms an essential field for studying PAHs removal from water resources. Ongoing investigation of novel adsorbents and the optimization of conditions is essential to provide an effective solution to mitigate the detrimental effects of PAHs on ecosystems and human health. A summarise report on the adsorption with different inducing factors has been explored in this chapter, which can be optimised and implemented to remediate PAHs efficiently, particularly from the various water resources.
