摘要: A thin film composite polyamide membrane having a porous support and a thin film polyamide layer comprising a reaction product of m-phenylene diamine (mPD) and trimesoyl chloride (TMC), characterized by the thin film polyamide layer having a critical strain value of less than 10%. In another embodiment, the thin film polyamide layer has a modulus of greater than 0.75 (GPa). In yet another embodiment, the thin film polyamide layer has an equilibrium swelling value of at least 45%. In another embodiment, the thin film polyamide layer has a thickness of at least 230 nm.

摘要: Method for determining total organic sulfur using reductive pyrolysis and specific electrochemical detection of sulfide ion at a mercury electrode. The method is especially useful for the determination of sulfur in matrices containing halogen or nitrogen compounds. Under routine conditions, a detection limit of less than 50 parts per billion (ppb) can be achieved using differential pulse cathodic stripping voltammetry as the detection mode.
