In this study, a strong acid gel cation exchanger (C100) impregnated with hydrated ferric hydroxide (HFO) nanoparticles (C100-Fe) was synthesized, characterized, and validated for application as a novel adsorbent to remove lead (Pb 2+) from industrial lead-acid battery wastewater.
The incorporation of lead into most consumer items such as gasoline, paints, and welding materials is generally prohibited. However, lead–acid batteries (LABs) have become popular and have emerged as a major area where lead is utilized. Appropriate recycling technologies and the safe disposal of LABs (which contain approximately 65% lead) and lead
Recycling lead from waste lead-acid batteries has substantial significance in environmental protection and economic growth. Bearing the merits of easy operation and large
Recycling lead from spent lead-acid batteries has been demonstrated to be of paramount significance for both economic expansion and environmental preservation.
These regulations specify the procedures and provisions applicable during the production, storage, distribution and recycling of lead-acid batteries. The purpose of this article is to describe the conventional effluent purification processes used for the recovery of materials that make up lead acid batteries, and their comparison with the
Spent lead-acid battery. Lead-acid battery (LAB) is widely used in the world as a chemical power source. LABs have a number of advantages, including being voltage stable, safe, reliable, inexpensive, useful in a wide range of applications, rich in raw materials and recycled at a high rate (Chen et al. 2009a).According to incomplete statistics, about 80–85% of the world''s
Recycling lead from spent lead-acid batteries has been demonstrated to be of paramount significance for both economic expansion and environmental preservation. Pyrometallurgical and hydrometallurgical approaches are proposed to recover metallic lead or lead oxide from SLP.
Lead can be removed from wastewater using a variety of treatment techniques, including chemical precipitation, adsorption, membrane filtration, ion exchange, and biological treatment (Fig. 10.2). These techniques can successfully eliminate Pb from wastewater and lower its concentration to allowable levels. The initial Pb concentration

In most countries, nowadays, used lead-acid batteries are returned for lead recycling. However, considering that a normal battery also contains sulfuric acid and several kinds of plastics, the recycling process may be a potentially dangerous process if not properly controlled.
Spent lead paste (SLP) obtained from end-of-life lead-acid batteries is regarded as an essential secondary lead resource. Recycling lead from spent lead-acid batteries has been demonstrated to be of paramount significance for both economic expansion and environmental preservation. Pyrometallurgical and hydrometallurgical approaches are proposed to recover
This technology overcomes the kinetic limits imposed by mass transfer barriers, improves reaction efficiency, and establishes an enhanced physical configuration for mass transfer. The new process provides a practical and feasible clean recycling method for waste lead-acid batteries that offers both environmental and economic benefits.
Lead (Pb) contamination in wastewater has frequently been reported, for instance the range of Pb contamination in water in the world varied from less than 0.001 mg/L to as high as 990 mg/L with an
The following paper aims to inform the readers about various hazardous wastes like solid waste, liquid waste and air pollutant generated in lead acid battery industries, harmful effects of those

Lead and lead oxides react with acid (excluding phosphoric and sulfuric acid) and base and it is inclined to form a covalent bond. Pb(II) ions are typically colorless in water and partly hydrolyze in Pb(OH) + and finally form [Pb 4 (OH) 4] 4+ where hydroxyl ions work as bridging ligands [15], [16] s sulfate salt is insoluble in water while lead nitrate (Pb(NO 3) 2)

Multiple requests from the same IP address are counted as one view. In this study, we present a low-cost and simple method to treat spent lead–acid battery wastewater using quicklime and slaked lime. The sulfate and lead were successfully removed using the precipitation method.
The method has been successfully used in industry production. Recycling lead from waste lead-acid batteries has substantial significance in environmental protection and economic growth. Bearing the merits of easy operation and large capacity, pyrometallurgy methods are mostly used for the regeneration of waste lead-acid battery (LABs).
The purpose of this article is to describe the conventional effluent purification processes used for the recovery of materials that make up lead acid batteries, and their comparison with the advanced processes already being implemented by some environmental managers.
The removal efficiency of lead was increased after using a carbonation step with 68% for quicklime and 69% for slaked lime. The carbonation process not only enhanced the lead removal efficiency in the battery wastewater but also reduced pH to meet requirements of environmental regulations.
It is evident that the segregation and independent treatment of the most polluting effluents from dismantling and washing lead-acid batteries means that much of the rest of the effluents can be discharged; this therefore simplifies their treatment and minimises the environmental impact.
The average concentration of lead in wastewater is about 3–15 mg/L and the pH of wastewater falls in the range of 1.6-2.9 [ 9 ]. If the battery wastewater is not treated well before discharge to environment, lead can contaminate food and water, and be present in nature.
