Paper Title:
Effects of Ca2+ Concentration on Calcium Carbonate Crystallization in Lignin Solution System
  Abstract

The calcium carbonate crystallization was controlled by Ca2+ concentrations, under the system of lignin solution with concentration of 10 g / L. Its morphology, structure and thermal decomposition were characterized by FT-IR, SEM, XRD and TG. Results showed that in lignin solution system, concentration of Ca2+ had significant effects on the crystallized morphology, orientation and crystallinity of calcium carbonate. Calcium carbonate crystal under low Ca2+ concentration had more uniform size while under high Ca2+ concentration which tended to form various sizes with more complete crystallization. The calcium carbonate crystals were all calcite calcium carbonate, which formed under different Ca2+ concentrations.
