Hence, based on the minimum specific gravity of industrial lead paste slurry, the concentration of desulfurizer required for sodium-calcium double alkali lead paste desulfurization was estimated to be at least 2.32 mol/L. 3.2. Mechanism of a novel process of lead paste pre-desulfurization
NaOH was used as the direct desulfurizer for lead paste, and lime was used to regenerate NaOH from the mother liquid at sufficient concentrations for desulfurization.
Lead-acid batteries contain 30% to 60% lead compounds and 10% to 30% acid (mainly sulfuric acid). According to the Identification Standards for Hazardous Wastes (GB5085-2007), waste lead-acid batteries are valuable hazardous waste, cannot be freely disposed of, and are not permitted to be imported or exported.
Lead–acid batteries are important to modern society because of their wide usage and low cost. The primary source for production of new lead–acid batteries is from recycling spent lead–acid batteries. In spent lead–acid batteries, lead is primarily present as lead pastes.
Adopt the surface update strengthens the alkali-making reaction. The traditional sodium desulfurization process for waste lead-acid batteries is beneficial to the environment; however, it is limited by poor economic viability as the cost of desulfurizer is much higher than the value of desulfurization by-products.
The desulfurization of lead paste by regenerated alkali was as follows: (i) desulfurization was conducted by adding waste lead paste to a beaker containing a certain volume of regenerated NaOH solution and stirred. (ii) After the desulfurization reaction was complete, filter residue and filtrate were obtained by vacuum filtration.

Improper waste lead-acid battery (LAB) disposal not only damages the environment, but also leads to potential safety hazards. Given that waste best available treatment technology (BATT) plays a major role in environmental protection, pertinent research has largely focused on evaluating typical recycling technologies and recommending the BATT ...
Recycling of spent lead-acid batteries (LABs) is extremely urgent in view of environmental protection and resources reuse. The current challenge is to reduce high consumption of chemical reagents. Herein, a closed-loop spent LABs paste (SLBP) recovery strategy is demonstrated through Na 2 MoO 4 consumption-regeneration-reuse.
From the perspective of recycling, waste lead-acid batteries have very objective utilization value. However, from the perspective of environmental protection, waste lead-acid batteries contain ...
