Organotin removal methods include water-soluble and solid-supported stannanes, catalytic methods, and alternative reagents based on less toxic metal and metalloid hydrides. Silica gel elution is one method to remove the organotins, followed by standard flash column chromatography to complete the purification. The second method does not require pretreatment of the product mixture because after concentration, the residue is eluted only by a stationary phase consisting of 10% finely ground potassium fluoride and 90% silica (w\/w). In this way, the content of organotin impurities can be reduced to below 30ppm. Organotin is a harmful substance that is difficult to degrade, so its existence in the environment will bring potential risks to human health and ecosystems. The following are several common organotin removal methods:<\/p>\n

<\/p>\n

1. Biodegradation method: This method uses microorganisms to decompose organotin molecules, which can be applied to water bodies and Organotin in the soil pollutes the site. However, biodegradation requires a long time and specific strains of microorganisms, making it difficult to operate. <\/p>\n

<\/p>\n

2. Chemical oxidation method: This method is to expose organotin compounds to strong oxidants (such as persulfate, potassium permanganate, etc.) , to oxidize organotin into harmless substances such as water and carbon dioxide. However, this method requires certain conditions, and the operation cost is relatively high. <\/p>\n

<\/p>\n

3. Adsorbent method: This method is to use adsorbents, such as carbon black, activated carbon, bentonite, etc., on organotin-contaminated sites to absorb organotin Molecules adsorb to the adsorbent material, allowing them to be removed from the environment. However, the adsorbent will cause secondary pollution to the environment, and the adsorbent needs to be replaced constantly. <\/p>\n

<\/p>\n

In general, different removal methods need to be selected according to the actual situation in the case of organic tin pollution, and several methods are often combined Combined use. <\/p>\n
