Abstract:
The migration of formaldehyde in melamineware were analyzed by investigating the influence of different marinating solutions, temperature, time, cutting size, microware treatment on the migration quality of formaldehyde from melamineware. Higher quality of migrated formaldehyde was found in the acid solution than in other solutions. Migration quality of formaldehyde rose abruptly above 80 ℃. A linearity relationship between soaking-treatment time and migration quality of formaldehyde was found. In addition, decreasing the granularity of melanmineware or increasing the microwave-treatment time (above 15 min) led to higher content of the migrated formaldehyde.
