Abstract

The search for sustainable resources remains a subject of global interest. Calcium acetate used in many fields was prepared using waste scallop shell as a raw material, and its physicochemical properties were investigated. The waste scallop shells were transformed to calcium acetate compounds by reactions with four acetic acid concentrations at ambient temperature until the completely dried powder is obtained. The maximum yield of 87% with short reaction time at a low temperature was observed in the reaction of 60%w/w acetic acid with scallop shells. Thermal transformation reactions of all prepared calcium acetate samples revealed temperature conditions for heating to produce other advanced materials. FTIR and XRD results confirmed the purity and solid phase of all prepared calcium acetate samples, and they were compared with those of literatures and found to be well consistent. The obtained timber-like particles have different sizes depending on the acetic acid concentration. This work reports an easy and low-cost method with no environmental effect to produce cheap calcium products to be used in the industry.

从扇贝壳中简单快速合成醋酸钙以减少环境问题

寻找可持续资源仍然是全球关心的一个问题。以扇贝废壳为原料，制备了多种用途的醋酸钙，并对其理化性质进行了研究。在常温下，通过与四种浓度的乙酸反应，将废扇贝转化为乙酸钙化合物，直至得到完全干燥的粉末。在低温条件下，以60%w/w的乙酸与扇贝壳反应，收率最高可达87%，反应时间短。所有制备的乙酸钙样品的热转变反应揭示了加热生产其他先进材料的温度条件。FTIR和XRD结果证实了所制备的所有乙酸钙样品的纯度和固相，并与文献进行了比较，发现两者具有很好的一致性。所得的类木材颗粒大小随乙酸浓度的不同而不同。本文报道了一种简单、低成本、无环境影响的生产工业用廉价钙产品的方法。
