Complete Style Fine Powder Polyacrylamide for Dyeing Wastewater Treatment

Jun 01, 2016 · Thus, the Ep was judiciously used as a CA in the CF of dye wastewater. The CA derived from Ep was prepared by oven drying of fresh Ep. The dried Ep was pulverized and mixed with deionized water and the mixture was heated in water bath, centrifuged and the supernatant was concentrated.

The present work deals with the removal of Brilliant Green dye from wastewater using a poly (acrylic acid) hydrogel composite (PAA-K hydrogel) prepared by incorporation of kaoline clay.

Apr 01, 2017 · The obtained white fine powder was applied in the same way as SC curing. Compared with SC curing, only about half the number of neutralized silicate powder (20–25% wt in comparison with 40% SC) results in unexceptionable curing (Fig. 7b) .

Aug 21, 2019 · Chromium exists mainly in two forms in environmental matrices, namely, the hexavalent (Cr(vi)) and trivalent (Cr(iii)) chromium. While Cr(iii) is a micronutrient, Cr(vi) is a known carcinogen, and that warrants removal from environmental samples. Amongst the removal techniques reported in the literature, adsorption Removal of chromium from aqueous solutions …

Jan 01, 2017 · Hybrid polyacrylamide polymer (Hy-PAM) was successfully applied in fine coal flotation to enhance the combustible recovery and reduce the ash contents of coal concentrates [2]. Base metaare mainly extracted from sulfide ores. Mostly these base metals tend to exist together in an ore.

Aug 28, 2020 · The samples and KBr were ground to a fine powder that was pressed into a pellet, which was then analyzed. 1 H NMR measurements of samples in D 2 O were carried out using a Bruker AVANCE DRX-500 spectrometer in proton noise-decoupling mode with a standard 5 mm probe at ambient temperature (25 °C).
