... experiments of Cs + and IO 3 − before and after the complexation of citrate with the pseudoboehmite surface were conducted to evaluate the effects of citrate on the adsorption of these ions on the surface of pseudoboehmite. Additional adsorption experiments of Cs + and IO 3 − after the decomposition...

...Figure 1. XRD patterns of the starting material and of the products synthesized at 220°C according to pH F . PB = Pseudoboehmite. ...

... has 4-fold coordination ( Berry and Mason, 1959 ); and γ-Al 2 O 3 has both 4- and 6-fold coordination ( Yoon et al. , 2004 ). Pseudoboehmite and SRO Al hydroxides were also selected as reference compounds for comparison. To synthesize Al hydroxide precipitates in the absence of carbonate, 1000...

...Shu-Qin Zheng; Shao Ren; Hong-Xia Yu; Jian-Ce Zhang; Wei Zhu Abstract Novel composite materials with wide pores were synthesized by an in situ technique using kaolin, palygorskite and pseudoboehmite as raw materials. The characterization results indicated that the synthesis components...

... of surface chlorite-like layers, covering the illite packets, however. The trend observed in the products of the reaction at 300°C was similar, except for the presence of boehmite or pseudoboehmite at the higher temperature. The values of the b parameter of illite, of the order of 9.12–9.16 Å, indicate...

..., differential thermal (DTA), and infrared analysis methods. Microprobe and DTA also suggested the presence of as much as 6% of sub-microscopic, noncrystalline alumina, probably in the form of pseudoboehmite. Cavity fillings and irregular veins containing chrysotile are as thick as 40 cm and commonly contain...
