Fast and Simultaneous Determination of Calcium and Phosphorous in Calcium Phosphate Based Bioceramics by ICP-AES

Abstract:

Calcium is generally determined by EDTA titration after separation of phosphate radicals, and the phosphorus is determined by weigh method. This traditional analytical process is time consuming and unfavourable for quality controlling. In contrast, the ICP-AES is simple and fast, and can simultaneously determine multielements. In this paper, the ICP-AES method was used to simultaneously determine calcium and phosphorous in calcium phosphate based bioceramics, and wavelengths of 317.933 nm and 213.618 nm were selected for the measuring of the calcium and phosphorus, respectively. The results obtained by ICP-AES are well consistent with the results determined by the traditional EDTA titration and weigh method, and suggest that the ICP-AES analysis is a simple, fast and accurate method for simultaneous determination of calcium and phosphorous in calcium phosphate based bioceramics.
