co-precipitation method: This method is the most commonly used synthetic hydrotalcite, the soluble divalent or trivalent metal ion salt (can be nitrate, sulfate, chloride) according to a certain proportion of mixed into metal salt solution, and then with alkali (can be sodium hydroxide, ammonia carbonate or urea) to adjust the PH, wait until the white hydrotalcite gel solution, then crystallization, washing, drying, hydrotalcite was obtained after grinding.
