“…MOFs often have a high degree of tenability, which may be done by a variety of metal ions and organic linkers, as well as post-synthesis surface changes. Because of their porous nature, they may be used for a variety of purposes, including natural gas and hydrogen storage [14,15] gas separation and recently in heavy metal removals from water and more [16,17,18]. Heterogeneity is introduced into MOFs as showed in Figure (1).…”

Copper is a heavy metal used in many industries and known for its negative impacts on the environment and human’s health. A novel structured metal organic framework (MOF) was used for copper adsorption for this work. SEM, EDAX, XRD and FTIR were done to confirm the structure of MOF prepared. MOF of 0.05 gm was used to examine its ability in Cu+ 2 removals with different initial concentrations of Cu+2 and pH values (5, 7 and 9). The prepared MOF was able to achieve Cu removal with 94.6%, 93%, 91.5%, and 92.5 % for the initial concentrations of 5, 10, 15, and 20 ppm respectively. It also performed very well for pH 5 and 7 with average removal ranging from 93.9%-95% for pH 5 and 7 for the initial concentrations of 5, 10, and 15 respectively which indicate that the prepared MOF is of high ability in Cu+ 2 removal.

“…So far, some studies report hydrogen adsorption in MMOFs at cryogenic temperatures. Very few ambient temperature hydrogen storage data on MMOFs are available [21]. Since the onboard storage of hydrogen at room temperature is most relevant for practical applications, we have systematically investigated hydrogen adsorption on LiÁCu 3 (BTC) 2 ,) were from E. Merck.…”

NaÁCu 3 (BTC) 2 and LiÁCu 3 (BTC) 2 (MOF) were synthesized using in situ sodium and lithium doping as hydrogen adsorbing materials. Phase stability and microstructure of the NaÁCu 3 (BTC) 2 and LiÁCu 3 (BTC) 2 materials were characterized by FT-IR, XRD, SEM, BET, and TGA. After in situ ions doping, the basic structures of NaÁCu 3 (BTC) 2 and LiÁCu 3 (BTC) 2 materials were not changed, but the surface area increased from 1300 to 1434 and 1445 m 2 g -1 , and the amount of hydrogen adsorbed increased from 1 to 1.4 and 1.6 wt% for NaÁCu 3 (BTC) 2 and LiÁCu 3 (BTC) 2 materials, respectively. Enhancement of hydrogen adsorption after sodium and lithium ion doping could be due to physical interaction (binding energy interaction) between hydrogen molecules and sodium ions and also due to increase of the surface area. It maybe that sodium and lithium ions act as an additional adsorption sites and adsorb hydrogen molecules.

This paper reviews the 40-year evolution and application of the magnetic suspension balance (MSB) and discusses some challenging issues of the technique. An MSB, as defined herein, is a magnetic suspension coupling (MSC) connected to an analytical balance. With an MSC, an object can be weighed in a different environment than the balance itself, making it possible for contactless weighing. Over the past 40 years, the MSB has been commonly used in research areas requiring accurate object weighings, notably gas density measurements by MSB-based densimeters and gas adsorption measurements by MSB-based sorption analyzers. More than 15 MSB-based densimeters have been built to date; these are generally called two-sinker densimeter and single-sinker densimeter. They have produced highly accurate density data of many pure fluids and fluid mixtures. These data serve as the basis for the development of reference equations of state, which play an essential role in various industrial and scientific areas. Moreover, such systems are central to the metrology program of many countries. The MSB technique is also very successful in adsorption science: more than 85 MSB-based sorption analyzers have been set up in over 20 countries. The number of new MSB-based sorption analyzers, and peer-reviewed publications resulting from them, are both increasing exponentially since 2004. They have produced highly reliable gas adsorption data at high pressures for many applications, mainly in the energy and environmental sectors. Although further development of innovative instruments based on the MSB is threatened by the proprietary nature of MSB technology, the development will continue, e.g., toward cryogenic measurements and a more compact design.
