Abstract: A shaped composite adsorbent made of a shaped porous material of a skin-core structure comprising a powdery ion-exchange type adsorbent and an ionic group-containing acrylonitrile polymer and wherein said shaped porous material has a semi-permeable skin layer of 0.01 to 1.mu. in thickness and a void volume rate of 50 to 90%, which is capable of adsorbing solutes present at low concentration with high selectivity and high yield. The shaped composite adsorbent of the present invention can be obtained by a process comprising dissolving an ionic group-containing acrylonitrile polymer in and dispersing a powdery ion exchange type adsorbent in an inorganic solvent for said acrylonitrile polymer, extruding the resultant into a coagulating liquid bath to effect coagulation-shaping thereof. The adsorption capacity and mechanical strength of the shaped composite adsorbent of the present invention can be further improved by subjecting the above-obtained coagulation-shaped material to heat treatment in a wet state, without drying.

Abstract: A humic product, such as ammonium humus crystallate or crystal humus acid is treated with an acid to esterify part of the hydroxyl groups, which are then etherified with the nonesterified hydroxyl groups. The resulting insolubilized humic material is amidated with an excess of a polyamine to produce an anion exchanger.

Abstract: Metal organic resins, composite materials composed of the metal organic resins, and anion exchange columns packed with the composite materials are provided. Also provided are methods of using the composite materials to remove metal anions from a sample, methods of using the metal organic resins as fluorescence sensors for detecting metal anions in a sample, and methods of making the metal organic resins and the composite materials. The metal organic resins are amine-functionalized metal organic frameworks and their associated counter anions. The composite materials are composed of metal organic resin particles coated with organic polymers, such as alginic acid polymers.
