Abstract
There is provided a method to characterize a sorbent. The method may provide a sorbent, suspend the sorbent in a fluid, stir the sorbent in the fluid, filter the sorbent from the fluid to isolate a filtrate, measure the electrical conductivity of the filtrate, and measure the alkalinity of the filtrate.
Claims11
A method of purifying a coolant that contains one or more conductive contaminants, comprising:
- contacting the coolant with a sorbent to thereby cause the sorbent to adsorb the one or more conductive contaminants,
- wherein the sorbent has a filtrate alkalinity of about 10 mg/L CaCO3 to about 60 mg/L CaCO3 and a filtrate electrical conductivity of less than about 650 μS, and
- wherein the sorbent comprises activated carbon.
A composition for purifying a coolant that contains one or more conductive contaminants, the composition comprising:
- a sorbent that has a filtrate alkalinity of 10 mg/L CaCO3 to about 60 mg/L CaCO3 and a filtrate electrical conductivity of less than about 650 μS,
- wherein the sorbent comprises activated carbon.
A method for making a sorbent for purifying a coolant that contains one or more conductive contaminants, comprising:
- providing a precursor sorbent material, and
- performing at least one treatment method on the precursor sorbent material to thereby form a sorbent that has a filtrate alkalinity of 10 mg/L CaCO3 to about 60 mg/L CaCO3 and a filtrate electrical conductivity of less than about 650 μS,
- wherein the sorbent comprises activated carbon.
