Abstract
A solid phase mixed solvent polymer, compositions and methods for removing and retaining solvated organic compounds and inorganic ions from water, wastewater, superficial and ground water, soil and other environmental sources, a soil amendment and method resulting from adhesively coating the polymer onto sand along with at least one ion exchange material, and methods for the containment, reduction, and prevention of organic leaching from soils, agricultural, industrial, and commercial environments, and in particular, sports and athletic turf facilities such as golf courses where pesticides are frequently applied.
Claims32
A method of making a solids phase mixed solvent polymer for adsorption and retention of solvated compounds, the method comprising;
- (a) reacting a ketone with a phenol to form a dialkyldiphenol;
- (b) methylolating said dialkyldiphenol with an aldehyde;
- (c) reacting a monoalkyl ether of PEG with phosphorous tribromide to form a monoalkyl PEG bromide;
- (d) reacting the products of steps (b) and (c) to form a monoalkyl PEG ether of the methylolated alkyl diphenol;
- (e) combining a phenol-aldehyde resole with said monoalkyl PEG ether of the methylolated alkyl diphenol to effectuate cross-linking.
A golf course green having the capacity to adsorb and retain solvated compounds and ions, to hold water, to enhance plant growth and having ion-exchange capacity without substantial reduction of percolation rate in said green, wherein said green includes one or more layers of a solid phase mixed solvent polymer composition comprising a polyoxyetheralkyldiphenol formed from the reaction between at least one polyoxyether, at least one alkyl diphenol, and a phenol-aldehyde resole, wherein said resole and said polyoxyetheralkydiphenol, are crosslinked and bound to a matrix.

- reacting a ketone with a phenol to form a dialkyldiphenol;
- methylolating said dialkyldiphenol with an aldehyde;
- reacting monoalkyl ether of PEG with phosphorous tribromide to form a monoalkyl PEG bromide;
- reacting said monoalkyl PEG bromide with said methylolated alkyldiphenol via the Williamson ether synthesis to form a monoalkyl PEG ether of the methylolated alkyl diphenol;
- combining a phenol-aldehyde resole with the monoalkyl PEG ether of the methylolated alkyl diphenol to form a mixture;
- coating said mixture onto sand particles;
- mixing a quantity of ion exchange material with said coated sand particles;
- and heating said coated particles to effectuate polymerization;
- and
- adding sail polymerized ion exchange coated sand particles to the soil to be amended.
A method for reducing leaching of organic compounds and ions from a soil, said method comprising:
- combining a phenol-aldehyde resole with a monoalkyl PEG ether of a methylolated alkyl diphenol to form a mixture;
- coating said mixture onto sand particles
- mixing a quantity of ion exchange material with said coated sand particles;
- and heating said coated particles to effectuate polymerization;
- and
- adding said polymerized ion exchange coated sand particles to said soil or turf in an amount effective to prevent leaching of said organic compounds or ions.
A process for separating solvated organic compounds and ions from an aqueous media that comprises the steps of:
- (a) combining a phenolic prepolymer with a PEG ether of a methylolated phenol to form a mixture;
- (b) coating said mixture onto particles;
- (c) crosslinking said mixture of step (b);
- and
- (d) contacting said aqueous media containing one or more organic compounds or ions with said particles after step (c) for a time period sufficient to bind said organic compounds or ions onto said particles.
A method for reducing leaching of organic compounds and ions from a soil, said method comprising:
- (a) combining a phenol-aldehyde resole with a monoalkyl PEG ether of a methylolated alkyl diphenol to form a mixture;
- (b) coating said mixture onto sand particles;
- (c) adding a quantity of ion exchange material to said coated sand particles;
- (d) mixing said ion exchange material and said coated sand particles of step (c);
- (e) polymerizing said mixture on said coated sand particles of step (d) and
- (f) adding said coated sand particles and ion exchange material of step (e) to soil or turf in an amount effective to reduce leaching of said organic compounds or ions.
A method for reducing leaching of organic compounds and ions from a soil, said method comprising:
- (a) combining a phenol-aldehyde resole with a PEG ether of a methylolated phenol to form a mixture;
- (b) coating said mixture onto a matrix;
