WebbA cationic starch flocculant was prepared from potato peel waste (PPW) for enhanced solid-liquid separation of livestock wastewater, thereby promoting the agricultural circular economy. The starch extracted from PPW was cationized by incorporating a cationic moiety onto the backbone of starch via etherification with (3-chloro-2 … Starch is often used in chemistry as an indicator for redox titrations where triiodide is present. Starch forms a very dark blue-black complex with triiodide. However, the complex is not formed if only iodine or only iodide (I ) is present. The colour of the starch complex is so deep, that it can be detected visually when … Visa mer The iodine–starch test is a chemical reaction that is used to test for the presence of starch or for iodine.
