The extract was filtered through Whatman filter paper no. 4 in vacuum and rinsed with the same to complete the transfer. The extracted oil was recovered after solvent evaporation in a rotary vacuum evaporator. The obtained oil yields were expressed in terms of the mass percentage of the sample...
the waste water is sequentially filtered by using a quartz sand filter, a precision filter, and an ultrafiltration membrane; and reverse osmosis desalination treatment is carried out; and c, non-permeate waste water in the reverse osmosis desalination treatment is subjected to low-temperature multi-...

A certain quality of the whole intestine sample was weighed, and 9 times the volume of 0.86% pre-cooled physiological saline was added to homogenize in an ice water bath, then centrifuged at 16000 r/min for 30 min, and the supernatant was used for intestinal enzyme activity analysis. The ...
Toward detecting the mechanical performance of LC@CF and LCPT@CF membranes during oil–water separation, the membranes were placed in ultrasonic water bath for 10 min at ambient temperature (Fig.6f), and then LC@CF and LCPT@CF membranes were used to separate the emulsion. As illustrated in ...
Hydroxy octadecanoic acid was prepared22via sulphating oleic acid, followed by hydrolysis. Where, sulfuric acid (15 ml, 96%) was added dropwise to a stirred cooled oleic acid (20 g, 0.07 mol) in an ice bath, after the addition was completed, the stirring was continued in the ice bath ...
Solid particles were removed using a centrifuge and water was removed by mixing CCO with 10 wt% silica gel followed by stirring the mixture and vacuum filtration using Whatman filter paper for the removal of silica gel [26]. This step was performed three times to ensure complete removal of...
With shallow well tests for Class A, B or C cements, simple water bath curing at atmospheric pressure and 100°F (38°C) is employed. For the basic cements of Class G or H not only is the same compressive strength test used as for Class A, B or C cements, but also a higher ...
