Three peloids were studied, prepared with three mineral-medicinal water (MMW) from the spas at Alicún (sulphate, rich in magnesium and calcium, highly mineralized), Zújar (sulphate, rich in sodium chloride, highly mineralized) and Graena (sulphate, rich in magnesium and calcium, highly mineralized) (province of Granada, Spain) and matured for three months, in order to determine their properties and suitability for use in pelotherapy. Their solid phase was prepared by mixing kaolin and bentonite (9:1, w:w). In the peloids the following was studied: composition of interstitial liquid, granulometry, physicochemical properties (specific surface area -SSA-, cation exchange capacity -CEC- and exchangable bases), crystallinity index of the minerals, thermal behavior and ultramicroscopic fabric using scanning electron microscopy (SEM) and image analysis (IA). A modification of the ionic concentration of the interstitial liquid was observed with regard to the initial MMW, namely, an increase in the concentration of Na+ and K+, and a decrease in Ca2+ and Mg2+, due to exchange between the exchangable cations of the solid phase and the ions of the MMW. Increases in the proportion of fraction <2 μm, SSA and CEC were also observed. The crystallinity index of the kaolinite decreased after three months' maturation, as compared to the initial mineral sample. The fabric developed during maturation was porous and reticulated and the fabric parameters were related to the thermal properties of the peloid. The properties of the three peloids studied make them potentially suitable for use in pelotherapy.

用格拉纳达(Granada)温泉中的三种矿泉水制成的仿制药。它们适用于远射治疗

研究了三种胶体,分别用来自Alicún(硫酸盐,富含镁和钙,高度矿化),Zújar(硫酸盐,富含氯化钠,高度矿化)和Graena(硫酸盐,富含镁和钙,高度矿化)(西班牙格拉纳达省)并熟化了三个月,以确定它们的性质以及是否适合用于深层治疗。它们的固相是通过混合高岭土和膨润土(9:1,w:w)来制备的。在胶体中进行了以下研究:间隙液的组成,粒度,理化性质(比表​​面积-SSA-,阳离子交换容量-CEC-和可交换碱),矿物质的结晶度,使用扫描电子显微镜(SEM)和图像分析(IA)的热行为和超显微织物。观察到相对于初始MMW,间隙液的离子浓度发生了变化,即Na浓度增加+和K +以及Ca 2+和Mg 2+的减少是由于固相的可交换阳离子与MMW离子之间的交换所致。分数<2μm,SSA和CEC的比例也有所增加。与初始矿物样品相比,高岭石的结晶度在三个月成熟后降低。在成熟过程中形成的织物是多孔的和网状的,并且织物参数与胶体的热性能有关。所研究的三种胶体的性质使其有可能适用于人体疗法。
