“…DEAE-cellulose (Diethylaminoethyl cellulose) is an example of a weak anion exchanger, where the amino group can be positively charged below pH ~ 9.0 and gradually loses its charge at higher pH values. A strong anion exchanger it is a strong base, which remains positively charged throughout the pH range normally used for ion exchange chromatography (pH 1.0-14) such as M500 resin witch loaded with chloride can be used for many analytical application [17].…”

THE DEVELOPMENT AND APPLICATION OF HYBRID SORBENTS FOR DETERMINATION AND SELECTIVE REMOVAL OF ARSENIC(III) AND ARSENIC(V) FROM WATER ABSTRACTThe aim of the thesis was the development and application of hybrid sorbents for determination of arsenic species in water and selective removal of arsenic from water. Water soluble arsenic species in natural water are inorganic (iAs) species, as arsenite, As(III) and arsenate, As(V).It is important to note that in neutral conditions, As(V) species are completely in ionic forms (H 2 AsO 4 -and HAsO 4 2-), while As(III) is in molecular form (H 3 AsO 3 or HAsO 2 ). This fact was the base for the application of anion exchange resin and selective hybrid resins for the separation, determenation and removal of iAs. As a result of anthropogenic pollution in water can be present organic (oAs) species as monomethylarsenic acid, MMAs(V) and dimethylarsenic acid, DMAs(V). Methods developed for iAs species should consider oAs species as interferences for the iAs determinations.In the frame of these tasks, efficiency of three types of resins were investigated: a strong base anion exchange (SBAE) resin and two hybrid (HY) resins, HY-Fe which integrates sorption activity of hydrated iron oxides (HFO) with the anion exchange function and HY-AgCl which integrates effects of chemical reaction with the anion exchange function. Two systems were employed: a batch and a fixed bed flow system. The selective bonding of arsenic species on three types of resins makes possible the development of the procedure for measuring and calculation of all arsenic species in water. In order to determine capacity of resins, the preliminary investigations were performed in batch system and fixed bed flow system. Resin capacities were calculated according to breakthrough points in a fixed bed flow system which is the first step in designing of solid phase extraction (SPE) module for arsenic speciation separation and determination.The investigations performed in the scope were focused on: I) separation of As(III) and As(V) species (in order to determine both arsenic species which are prevailing in natural waters), II) separation of organic arsenic species (in order to determine of DMAs(V) and MMAs(V) in natural waters) and III) collection, preconcentration and removal of all arsenic species.The main achievement of thesis is that three methods for arsenic species determinati...

Water is an integral part of life on earth. Rapid industrialization, urbanization, and population explosion have all contributed to the pollution of ground and surface water with, among other things, heavy metals. This has led to an acute shortage of clean drinking water. Arsenic is one of the most toxic heavy metals found in water, posing a serious threat to the environment, human beings, and aquatic life. Over the years, a considerable amount of research has been directed toward the elimination of arsenic from water via sustainable methodologies. Metal organic frameworks are a class of materials possessing exceptional features like chemical stability, high porosity, multiple functional groups, and large surface areas. These properties can be effectively channelized to make metal organic frameworks excellent adsorbents for the removal of arsenic from contaminated water and make it drinkable. We have reviewed herein, the problems of heavy metal contamination, specifically the different forms of arsenic that pollute water. The importance of metal organic frameworks and the progress made in the synthesis of materials having a metal oxide framework have been discussed. Significant properties like adsorption and mechanistic aspects of adsorption through metal organic frameworks have been described. Furthermore, the characterization of the electronic and geometric aspects
