摘要:
A water treatment system comprises at least one electrolytic cell comprising at least one electrode and a power source for powering the electrode. The electrode may be a metal electrode comprising a coating of polymer comprising structural units of formula I (I) wherein R 1 is independently at each occurrence a C 1 -C 6 alkyl radical or -SO 3 M wherein M is independently at each occurrence a hydrogen or an alkali metal a hydrogen or an alkali metal, R 2 is independently at each occurrence a C 1 -C 6 alkyl radical, a is independently at each occurrence an integer ranging from 0 to 4, and b is independently at each occurrence an integer ranging from 0 to 3. An associated method is also described.
摘要:
A method for water treatment, includes: contacting water with an effective amount of a composition comprising a polymer derived from a first monomer of formula I: (formula I), and a second monomer selected from : (formula), and (formula), to obtain a treated water with reduced chemical oxygen demand; and separating the treated water from the composition; wherein, a weight percentage of the first monomer to a total of the first and the second monomers is in a range of from 0 to 90%; R 1 , independently at each occurrence, is, H, C 1 -C 18 alkyl, alkoxyl, or phenyl; R 2 is C 1 -C 18 alkyl, alkoxyl, or phenyl; and a is an integer ranging from 0-4. An associated composition and a method for preparing the same are also described.
摘要:
A method comprises: sorbing a sample solution comprising nucleic acids to a sample receiving portion of a quartz fiber filter by contacting the sample solution with the sample receiving portion; and washing the sample receiving portion while keeping most of nucleic acids around the sample receiving portion by flowing a wash solution through the sample receiving portion under a wicking force directed away from the sample receiving portion. An associated apparatus is also provided.
摘要:
The present disclosure provides methods of preparing a thin film composite membrane using gas-phase molecular-layer-by-layer deposition of reactive organic compounds, and thin film composite membranes. Depending on characteristics of the membrane and microporous support, the composite membrane may be used in RO, NF, FO, pervaporation, or gas separation processes.
