Lead is a common hazardous heavy metal found in agricultural soil and industrial wastewater. It is a dire need for society to remove lead from wastewater via a facile and cost‐effective route, which is needed to improve water quality. Here we obtain boron (B) doped porous carbon (BC) via two‐step thermal pyrolysis of waste tires, as it is a promising raw material. The B doping changes the coordination chemistry, physicochemical properties, and surface structure of carbon. The degree of graphitization, boron content, and pore size distribution of BC was controlled by thermal treatment and NaBH4 content. The surface topography, elemental composition, degree of graphitization, chemical structure, and lead (Pb) removal efficiency of BC was thoroughly analyzed by SEM, EDS, Raman, XRD, XPS, and ICP‐OES analysis. Benefiting from the structural disorder, high specific surface area, and least coordinated exposed carbon, the BC revealed high adsorption efficiency (98.02 %) for lead removal from wastewater.
Pakistan is vulnerable to smog from the last two to three years especially in winter season and it produces haze in the atmosphere which is ultimately vanishing due to rain and it badly affects the public.Smog is related to air pollution and it causes eyes, nose, lung, throat infection which is allergic one and spread rapidly and causes fever and skin diseases.In this article number of factors and reason behind that are vehicle emission, urbanization and burning of waste are discussed and how to mitigate and prevent our atmosphere.So there is a need to copeup this problem through long term planning that is better for the public and for our future generation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
