1.The binary and ternary stability constants of DL-α-Alaninc with Cu(Ⅱ),Zn(Ⅱ),Ni(Ⅱ) and Cd(Ⅱ) were determined by pH polcntiometric titration at 37±0.1℃ and ionic strength 150mM/dm3.Potentiomeinc data were treated with ZPLOT,MAGEC,MINIQUAD and ESTA programs. The compositions of complex species were ascertained in the complex equilibriums by selection of different chemical models.
2.Applying the computer program MINIQUAT and ESTA to the titration data the best chemical species models have been chosen in each systems and stability constants at physiological conditions (37±1°C and ionic strength I=150mmol·dm~(-3)NaCl) have also been determined.
6.muddiness created by stirring up sediment or having foreign particles suspended.
7.T he hollow particles of Y(OH)CO 3 (see Fig.5)were prepared by the coordi-nation reaction which dissolved the pre-existing particles of AgI in Na 2 S 2 O 3 concentrated solutions.
8.The laminations are usually bonded together by adhesives, but other forces could be used, such as those provided by welding.
9.The morphology and phase of cadimum sulfide nano-particles are delected by SEM and X-ray diffraction. The results show that the CdS nano-particles are spherical and spinulous respectively. The spherical particles are poor crystalline with somewhal of oxidation, and the spinulous particles are wurtzite structure.
