Analysis of heavy metal content in various batteries

Analysis of heavy metal content of various batteries: Lithium batteries, etc., will accumulate a pile of old batteries when using wireless mice, electric toothbrushes, electronic watches, and remote controls. Existence also troubles, giving up also troubles, dilemma, I don't know how to deal with it. Because cadmium is a heavy metal, it is similar to calcium in bone structure. Cadmium can cause bone pain when it enters the human body. Other zinc-manganese dry batteries and button batteries cover the zinc electrodes with mercury to prevent hydrogen explosion when the battery is not in use. This is why there has been a movement to recycle used batteries since the 1970s. The smog has raised our environmental protection knowledge to a very high level. The publicity of the recall of used batteries is well known. With the continuous development of battery technology, should we stick to the ancient ropes? It is said that the public can see batteries at the earliest. Use alkaline dry batteries (including but not limited to: AA, AAA: 5, 7C: no. 2, D:1, 9 volt batteries, usually used for alarms, suitable for products with longer battery life), button batteries (electronic watches Etc.), lead batteries (electric bicycles, cars, etc.), lithium batteries (mobile phones, computers, cameras, etc.), and discrete power supplies (UPS). According to the 12th Five-Year Plan for the Prevention and Control of Heavy Metal Pollution, the important pollutants for the prevention and control of heavy metal pollution in my country are lead, mercury, cadmium, chromium, and arsenic. Most people feel that battery recovery is unpreventable. They think that the battery is equivalent to pollution. Suppose you tell them that it was announced on October 9, 2003. The policy on waste battery pollution prevention and control technology has clear rules. Since January 1, 2005, the continuous processing of mercury, or more than 0.0001% of alkaline zinc-manganese batteries, will be withdrawn. In other words, the economic conditions are useful, and it is not encouraged to collect the low or mercury-free batteries that have met the national requirements and waste time. They will definitely be a little surprised. Suppose you tell them that the Ministry of Environmental Protection and the National Development and Reform Commission announced a rule on June 6 that the waste nickel-cadmium batteries and mercury oxide batteries that occurred in 2008 can be mixed and buried in daily household waste instead of as a danger. Waste, they may shake their heads. So why do we have battery recycling problems in schools? The ubiquitous battery collection box is just like this? Can waste batteries be discarded together with domestic garbage? The main market is the most common thing we encounter For this reason, batteries and alkaline manganese batteries account for about 80%, because its mercury content has been controlled by the relevant rules of the country, and no environmental pollution is seen, and it will not follow the food chain to enter the human body. We can treat it as a Solid waste, waste disposal. What batteries do you want to bring back? First, we must resolutely recall the fake batteries processed in the small workshop. Others, such as lead-acid batteries, because it contains heavy metal lead, may increase the lead concentration in human blood when put into the environment, which will affect human intelligence; except for lead-acid batteries, nickel-cadmium batteries, rechargeable batteries, button batteries (dry batteries do not The mercury ban master plan still allows the presence of small amounts of mercury and other batteries during the day to be recalled in accordance with the US Environmental Protection Agency's instructions. Maybe you have heard of or experienced car battery theft, because lead batteries can be sold for more than 100 yuan; the clean processing standard waste lead-acid battery lead recycling industry, which took effect on January 1, 2010 pointed out that the recycling rate of lead-acid batteries is related Qualified companies must reach more than 95%, and even some companies using advanced equipment can reach 98%. This is a positive example of battery recovery. However, because lead-acid batteries contain about 74% lead plates and 20% sulfuric acid, there are huge benefits to encourage some small workshops to quietly restore and dismantle, directly remove lead plates, dump waste acid, and the recovery rate is not high, but it also causes water. And soil pollution, the lead ions dissolved in the acid enter the environment. This has also sounded the alarm for the recycling of used batteries. Recycling is a good thing, and supervision is a major event. It cannot constitute pollution while recycling pollutants.
