The NOM from hard water streams has been isolated using reverse osmosis and electrodialysis in tandem. [ 16 ] Extracted humic acid not a single acid ; rather, it is a complex mixture of many different acids containing carboxyl and phenolate groups so that the mixture behaves functionally as a dibasic acid or, occasionally, as a tribasic acid .
Natural gas leaks happen nearly every day in the U.S. — and they can be deadly if they go undetected. A report from a group of Texas environmental nonprofits released in June found around 2,600 ...
