The Bayah (Lebak, West Java, Indonesia) zeolites can also adsorb crude oil spill
(Kalbuadi et al. 2019). Addition of a 100-mesh zeolite powder at 1:2 (w/v) ratio
could adsorb the oil up to more than 86%, and promote a stable flocculation of crude
oil spill. Oil adsorbing capacity is improved by the addition of a bacterial inoculum
B. subtilis.
Thus, as Bayah zeolite is composed of high molecular sieves structure, it has
excellent various functions mentioned above. The X-ray diffractogram of the Bayah
zeolite shows a dominated Clinoptilolite mineral as shown by several peaks at
10, 22, and 28
2-θ (Fig. 10.2 above), and the scanning electron microscope
shows high molecular sieves structure (Fig. 10.2 below). The physical-chemical
characteristics of Bayah clinoptilolite zeolite are shown in Table 10.1. The Bayah
clinoptilolite zeolite is summarized as a porous material with high molecular sieves
structure, which causes high CEC, high content of K
+
, high water holding capacity,
and high content of organic matters (however, humic and fulvic acids probably will
be lost on ignition).
