This study presents a zero-valent iron / activated carbon fiber felt (ACFF) galvanic couples (Fe0/ACFF) process to remove dissolved phosphate from water. The effect of initial phosphate concentration and pH were investigated, and the adsorption capacity and kinetic model were also evaluated using both the Freundlich and the Langmuir isotherm models and the Lagergren model. The results showed that...
Logical key tree is an important issue for multicast key management. The degree of a tree and the algorithm which maintains the balance has great effect on the multicast key management. The paper makes an analysis on the key tree degree with using hierarchical data processing model. The complete quad tree is taken as the logical structure of the key management, and the rebuilding algorithm of a complete...
