Synthesis and flocculating properties of cationic starch derivatives
The Spectra of starch, cationic starch derivatives S-GODAC, S-GDDAC, and S-GTDAC are indicated in Fig. 1 a–d. The broad band (Fig. 1 a) at 3400 cm −1 is due to the stretching mode of the O–H groups.Peaks at 1154, 1082, and 1022 cm −1 are the characteristic absorption bands of starch backbone. For cationic starch derivatives S …

The Ultimate Guide to Pool Flocculants: Do and Don't While …
The flocculant does not treat algae, so you need to kill it first and then remove cloudiness with the flocculant. While using you should strictly follow the instruction on the bottle. The most critical steps are (1) turning on the pump for 1-2 hours to distribute the floc and (2) setting the filter "to waste" while manually vacuuming.
