All materials used were of reagent grade and from commercial sources. Iron (III) sulphate hydrate, iron (II) sulphate heptahydrate (ACS, 99+%), and citric acid (99+%) were purchased from Alfa Aesar (Haverhill, MA, USA). Acetone (AppliChem GmbH, Darmstadt, Germany), ethanol absolute (Carlo Erba Reagents GmbH, Emmendingen, Germany), NH4OH (aq) 25% (Honeywell Fluka, Charlotte, NC, USA), and HCl 1 M (Honeywell Riedl-de-Haën, Charlotte, NC, USA) were used as received. Polyethylene oxide (PEO; Mw, 400,000 g/mol) was from Sigma-Aldrich, Co. (St. Louis, MO, USA), and poloxamer 188 (P188; Lutrol F68) was from BASF (Ludwigshafen, Germany). The water used was purified by reverse osmosis.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
