The preparation of NIPs is safe,  simple, and inexpensive. However, these tiny  particles cannot be used in fixed-bed columns or in  any plug flow type configuration due to excessive  pressure drops and poor durability. Harnessing these  NIPs within polymeric beads offers new opportunities  in the area environmental separation and control. In  this study two materials were dispersed with the  NIPs: hybrid anion exchanger (HAIX)and dual zone  sorbent (DZS). DZS particles, in addition to being  magnetically active, are capable of selectively  removing Cu(II), As(V), As(III), and DCP. DZS also  showed favorable regeneration efficiency using a two  step procedure.    Sorption tests proved that HAIX beads were selective  for both As(III) and As(V). HIX particles were also  amenable to efficient regeneration. HAIX also ran  well with groundwaters contaminated with arsenic.  Kinetic studies confirmed that intraparticle  diffusion was the primary rate-limiting step for As (V) sorption.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783843374286\"\u003e\u003ch3\u003eCHARACTERIZATION AND ENVIRONMENTAL APPLICATIONS\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783843374286","offer_id":39470114078813,"sku":"9783843374286","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/b4721fb2-ddcf-49df-949d-5e0ad6391b99.jpg?v=1770447632","url":"https:\/\/shop.autorenwelt.de\/en\/products\/polymer-supported-hydrated-fe-oxide-hfo-nanoparticles-von-luis-cumbal","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
