Disclosed are novel ion-exchange and chelateexchange resins having improved exchange kinetics for separating chemical species from liquids. The resins are prepared from copolymer beads consisting of a monovinyl aromatic monomer and a cross linking monomer. The copolymer beads are functionalized such that weakbase exchange moieties are substituted at haloalkylated sites which are most accessible to diffusion into the beads, while hydrophilic, strong-base exchange moieties are substituted at haloalkylated sites which are least accessible to diffusion. The resins have improved exchange kinetics due to shortened diffusion path lengths for the chemical species being separated and improved diffusion into the resin beads due to the hydrophilic, strong-base exchange moieties. 37,506-F ...

The present invention relates to a metal adsorbent used for removal/collection of a wide variety of heavy metals in treated solutions such as industrial wastewater, service water and environmental water.Chelating resins are used as adsorbents/collectors of heavy metal elements in a solution containing a high-concentration salt, which are difficult to adsorb and collect with ion exchange resins. As the ability of forming a complex with metal elements varies depending on the structure of functional groups, chelating resins having various functional groups such as an iminodiasetic acid (IDA) group, a low-molecular polyamine group, aminophosphoric acid group, an isothionium group, a dithiocarbamic acid group and a glucamine group are commercially available. Among them, chelating resins introducing an IDA group are mainly used, but chelating resins introducing a low-molecular polyamine group are used for removing metals from a solution containing a large amount of alkali metals and alkali earth metals. These chelating resins form a complex with many metals, but the stability constant of a complex formed is significantly low as compared to ethylenediamine tetraacetic acid (EDTA), a typical chelating agent, and there arises a disadvantage that metal removal and collection rates are subject to ...

A composite, time-delayed, polymer-coated, granulated material for maintaining hydration in plants is formulated to delay acceptance of water in order to operate in drilling, plugging, and disking equipment used for aeration, soil amendment, or both. Whether potted or outdoors, whether relying on a third-material binder or a small, hydrated portion of the polymer itself as a binder, the material may be injected or otherwise placed below the surface of soils. Water is eventually absorbed sufficiently to expose the bulk of the hydrating particles attached to each granule. Addition of the granulated material as a soil amendment resists dehydration normally occurring in plants between waterings, yet its initial delay in hydrating supports water-jet injection and soil integration by resisting premature expansion from hydration. 1. A method for treating soils , the method comprising:providing a hydrator, comprising a carrier formed as granules, an absorber disposed on a surface of the carrier, and a repellant applied to the absorber to resist absorption of water thereby for a preselected period of time;selecting a soil location;providing a cavity in the soil;positioning a quantity of the hydrator in the cavity;applying water to the soil location during the preselected period to integrate the hydrator into the soil and to close the cavity to resist escape of the hydrator upon eventual absorption of water by the absorber;penetrating by water the absorber to substantially destroy the ability of the repellant to resist absorption of water by the absorber;providing water to the soil subsequent to the preselected period to hydrate of the absorber; andmaintenance of a portion of the water by the absorber after drying of surrounding soil proximate the soil location.2.
