Catalytic and Adsorbent Properties of Solid Acid Catalysts Studied by Ammonia Adsorption Microcalorimetry by
Solid acid catalysts are becoming of great importance within the chemical industry and their acidity is of great interest, as this determines their application, plus many of their catalytic properties can also be directly related with their acidity. There has been a drive towards heterogeneous solid acid catalysts because of the environmental concerns with safe handling and disposal of mineral ...
متن کاملInhibition of biohydrogen production by ammonia.
Ammonia inhibition of biohydrogen production was investigated in batch and continuous flow reactors with glucose as a substrate. In batch tests, biohydrogen production rate was highly dependent on pH and ammonia (defined as the sum of NH3 of NH4+ species) concentrations above 2 g N/L. At pH = 6.2, the maximum production decreased from 56 mL/h at 2 g N/L to 16 mL/h at 10 g N/L. At pH = 5.2, prod...
متن کاملVermicompost as a Natural Adsorbent Material: Characterization and Potentialities for Cadmium Adsorption
Amostras de vermicomposto (material húmico) foram submetidas à caracterização por espectroscopia de infravermelho, difractometria de raios-X, termogravimetria, microscopia eletrônica, entre outras; adicionalmente, foi determinada a capacidade de troca catiônica (CTC). Empregou-se planejamento fatorial para estudar os mecanismos de interação da espécie Cd com os sítios adsortivos do vermicompost...

Adsorption of arsenic(III) and arsenic(V) from groundwater using natural siderite as the adsorbent.
Batch and column tests were performed utilizing natural siderite to remove As(V) and As(III) from water. One hundred milligrams of siderite was reacted at room temperature for up to 8 days with 50 mL of 1000 microg/L As(V) or As(III) in 0.01 M NaCl. Arsenic concentration decreased exponentially with time, and pseudoequilibrium was attained in 3 days. The estimated adsorption capacities were 520...
