The result shows that humic acid has better treatment result for phenol-containing waste water treatment. At pH value=1.0 and when adsorption is conducted at room temperature for 12h, the adsorption rate can reach over 95%.
Results The removal efficiencies of formaldehyde in indoor air were 82.94%, 91.43%, 95.69%, at the 24th, 48th, 72th hour after the treatment of formaldehyde-cleaning agent respectively. The formaldehyde concentration in indoor air of test room met the requirement of the national standard after 72h-treatment of formaldehyde-cleaning agent.
The concentration of formaldehyde,benzene,and ammonia indoors air of different layers was no significant(P＞0.0.5),but the concentra- tion of formaldehyde,benzene,and ammonia indoors air of different type room in same layer was significant(P＜0.05).
The results showed that the,sarisfaction'answers to the inner height of the ward,the number of beds in the room and the distance of near beds were 33.6～66.9%,but a ward with larger personal space would be more welcome by inpatients.
The interaction between 18-methyl norethindrone and ketoprofen, including the displacement of ketoprofen from human serum albumin binding sites, was investigated by the capillary electrophoresis-frontal analysis method (CE-FA) at room temperature.
The crystal energy of ionic liquid is much lower than ionic solid and this is the underlying reason for forming ionic liquid at room temperature.
The reaction process was monitored by the temporal evolution of the UV-Vis absorption and room temperature photoluminensce spectra.
The samples were characterized by XRD, BET, DTA-TG, UV-Vis, and their photocatalytic properties were evaluated with two model pollutants, methylene blue (MB) and rhodamine B (RB), at room temperature.
The P-E hysteresis loops are measured by means of the Sawyer-Tower test system with a compensation resistor at room temperature.
