21. Notable examples of prospective applications are catalysis, sorption , gas sensing, ion exchange, optics, and photovoltaics. 22. The "'piezoelectric sorption "'instrument compares the changes in frequency of hydroscopically coated quartz oscillators. 23. Selective sorption topics covered include the modification and utilization of biosorbents and the use of selective ligands for metal sorption. 24. Selective sorption topics covered include the modification and utilization of biosorbents and the use of selective ligands for metal sorption . 25. The journal also publishes research on hybrid processes combining ion exchange and waste minimization in ion exchange and sorption processes. 26. Industrious biosorption is often done by using sorption columns as seen in "'Figure 1 " '. 27. Soil sorption is proportional to carbon chain length, with a length of 14 and more having the highest sorption rate. 28. Soil sorption is proportional to carbon chain length, with a length of 14 and more having the highest sorption rate. 29. Although water sorption experiments are most common, the use of organic vapor in DVS experiments can reveal additional sample properties. 30. Then a sorption pump would be used to bring the pressure down to 10 " 4 Torr ( 10 mPa ).
