Preparation of Calcite, by biomass-derived incineration of phyto-capped, marine gastropod shell Turbinella pyrum L is described. Turbinella pyrum shell is mechanically hard, characterized as Aragonite, was phyto-capped and incinerated to prepare Calcite powder, of nano-micro sizes. The role of phyto-constituents in the phyto-capping, is attributed to the increase in the internal pressure, perceived by release of intercalated organic moieties, resulting in the reduction of particle size in comparison with uncapped process. The incineration process was optimized by solid state UV-DRS whereby, the absorption in the region 400–700 nm was considered for process optimization, which may be attributed to the strong π to π* ligand transitions of chlorophyll. The gastropod shell of marine origin was purified in high alkaline medium, to remove/reduce the associated trace impurities present in the complex marine environment, such as barium, aluminium and magnesium into their respective carbonate salts, and was quantified by ICP-OES. FT-IR, FT-Raman and PXRD techniques were used for characterization. SEM revealed agglomerated non-uniform nano and micro particles. Calcite, is known as ‘Sangu Parpam’, in the traditional Siddha system of medicines used in India and is one of the classical formulations used to treat arthritis, gastritis, skin diseases.

由植物封顶的海洋腹足动物壳,Turbinella pyrum L ,生物质衍生的方解石热制备

描述了通过生物量衍生化的植物封端的海洋腹足动物壳的Turbinella pyrum L来制备方解石。Turbinella pyrum壳是机械坚硬的,具有文石特征,被植物封盖并焚烧以制备纳米级方解石粉末。植物成分在植物封端中的作用归因于内部压力的增加,内部压力的增加是由嵌入有机部分的释放所感知的,与未封端的过程相比,导致了粒径的减小。通过固态UV-DRS对焚烧过程进行了优化,从而可以考虑在400-700 nm范围内的吸收进行过程优化,这可能归因于叶绿素从π到π*的强过渡。在高碱性介质中纯化了海洋起源的腹足动物壳,以将复杂的海洋环境中存在的相关痕量杂质(例如钡,铝和镁)去除/减少到它们各自的碳酸盐中,并通过ICP-OES进行了定量。FT-IR,FT-Raman和PXRD技术用于表征。SEM显示聚集的不均匀的纳米和微粒。方解石,被称为“Sangu Parpam '是印度使用的传统Siddha药物系统中的药物,是用于治疗关节炎,胃炎,皮肤病的经典制剂之一。
