The study of adsorption behavior of the gels for  some precious and base metals revealed that they  were highly selective for Au(III) with competitive  adsorption capacity. CLP exhibited outstanding  selectivity for Au(III) since it was almost inert  towards other metals. Furthermore, it reduced Au (III) to Au(I) and finally to elemental gold making  it easier for recovery. On the other hand, CLC  exhibited high selectivity for various heavy metals  with high efficiency, recyclability and stability.  In addition, CLP was further functionalized to EN¿ lignin, PA¿lignin, and DMA-lignin. The derivatives  show high selectivity for Au(III), Pd(II) and Pt(IV)  with high loading capacity and almost no adsorption  for other metal ions. Thus, by the present study,  novel uses of wasted wood material have been  developed in the form of economic \u0026amp; environment  friendly adsorption gels.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838376288\"\u003e\u003ch3\u003estudy on the total recovery of precious metals and removal of toxic metals from indutrial waste waters\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838376288","offer_id":39498947559517,"sku":"9783838376288","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/0bf2a029-e210-4c07-ae3d-91a59d6fda7d.jpg?v=1773384659","url":"https:\/\/shop.autorenwelt.de\/products\/development-of-lignin-derivatives-for-the-recovery-and-removal-of-metals-von-durga-parajuli","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
