Catalonia Fine Powder Type Temperature-Resistant Salt-Resistant Polyacrylamide for Petroleum Mining Wastewater Treatment

Jan 26, 2021 · Identification of salt stress responsive and MIR-based genes in wheat. Salt- responsive genes have been well characterized in crop plants 22,23,39,40 as shown in Supplementary Table S2 and ...

Application experiments for wastewater treatment were carried out consequently, and the optimal dosage of cationic pea starch was 40 mg/L within the pH range 6–8.

May 25, 2021 · The injection volume in split mode (split ratio 1:10) was 0.5 µl with the injector temperature at 250 °C, and the gaz carrier was He at 36.5 cm/s. interface temperature, 280 °C; ion source temperature, 250 °C; mass range, m/z 50–600; scan speed, 2500 amu/seg; and event time, 0.20 seg., were the MS detection parameters employed for the ...

Nov 19, 2019 · The salt tolerance values of synthesized copolymer solution at 5000 ppm copolymer concentration at 303 and 343 K are 20 and 25%, respectively. This is performed by gradually increasing the percentage of salt (NaCl) in aqueous copolymer solution until precipitation is observed. Salt tolerance is observed to increase with temperature.

Delta ferrite-containing austenitic stainless steel resistant to the formation of undesirable phases upon aging. DOEpatents. Leitnaker, James M.-01. Austenitic stainless steel alloys containing delta ferrite, such as are used as weld deposits, are protected against the transformation of delta ferrite to sigma phase during aging by the presence of carbon plus …
