In this paper, we have studied the behaviour of extraction of pal-ladium( I ) by Di-(2-ethylhexyl) sulfoxide ( DEHSO ) at low acidity medium. The effects of [H+], [C1-] and temperature on the distribution ratio have been investigated. When the concentration of the extractant is higher ([DEHSO](0):[Pd2+]>2:l), the reaction is

L-type molecular sieves were synthesized with four different silicious materials, namely silica sol, silica gel, waste silica sludge and kieselguhr. All the samples obtained were examined with X-ray diffraction, isothermal adsorption of water, DTA, TG, IR, TEM, and chemical analysis, and were identified as L-type molecular sieve. The crystaltinities of sieves can be obtained from the formula: (A_(sample)-A_(gel))/(A_(standard sample-A_(gel)), in which the A_(sample), A_(gel), and A_(standard sample) represent...

L-type molecular sieves were synthesized with four different silicious materials, namely silica sol, silica gel, waste silica sludge and kieselguhr. All the samples obtained were examined with X-ray diffraction, isothermal adsorption of water, DTA, TG, IR, TEM, and chemical analysis, and were identified as L-type molecular sieve. The crystaltinities of sieves can be obtained from the formula: (A_(sample)-A_(gel))/(A_(standard sample-A_(gel)), in which the A_(sample), A_(gel), and A_(standard sample) represent the amount of adsorbed water of the sample, the gel and the standard sample, respectively. In calculation, the values of A_(sample) and A_(gel) were measured in each experiment, and the value of A_(standard sample) was taken from literature as 12.6%. At a constant crystallizing temperature of 150℃, with the crystallization time for silica sol, silica gel and waste silica taken as 32 hrs, 45 hrs and 45 hrs, respectively, the crystallinity of each sieve obtained was found to be 98%, 92% and 89%, respectively. As for the kieselguhr (pre-washed with water), when the crystallizing temperature was maintainted at 130℃ and the crystallizing time was taken as 40 hrs, the crystallinity of the sample was 63%.
