ABSTRACT
Zeolite Clinoptilolite from Lampung, located in South of Sumatra, had
been modified with surfactant hexadecyltrimethylammonium bromide (HDTMA-Br) as chromate anion exchanger. Surfactant modified zeolite (SMZ) Clinoptilolite in particle size range of 1.5 - 2.0 mm, which contained 196.7 mmol HDTMA-Br/kg zeolite, was used for anion exchange of chromate at neutral pH. This experiment was conducted in a glass column filled with 5 gram SMZ. The breakthrough chromate exchange capacity was found 1.262 mg/g SMZ, while the ...

A medical system whether traditional or modern, is a long chain of processes of humanstrategy for adapting to their ecological bio-cultural environment. Naturally humans developtheir biological ability to sustain their kind and develop many adaptation strategies, creatingmedical systems, behavior, and belief sbased on culture as a natural response to the treat ofillness and disease, even though the result of certain behavior does not guarantee the healingof such illness and disease (Dunn in Foster-Anderson, 1986; p.41). ...

In order to enhance adsorption capacity of gibbsite (Al(OH)3 as an adsorbent for the adsorption of phosphate in water, gibbsite was modified through lithium-intercalation. The purification method of Tributh and Lagaly was applied prior to intercalation. The Li-Intercalation was prepared by the dispersion of gibbsite into LiCl solution for 24 hours. This intercalation formed an cationic clay with the structure of [LiAl2(OH)6]+ and exchangeable Cl- anions in the gibbsite interlayer. A phosphate adsorption test using ...
