Pyrolusite is widely used as desulfurization materials for sulfide-containing wastewater, sulfide-containing waste gas, biogas and process gas. However, some studies on the characteristics and applications of its desulfurization products still are lack. This paper simulated the conditions of wastewater desulfurization, normal temperature waste gas desulfurization and high-temperature desulfurization of process gas to obtain the corresponding pyrolusite sulfide products, and investigated the phase composition of sulfureted pyrolusite in different ways and the effect of cadmium removal from wastewater and its mechanism. The effects of solution pH value, initial cadmium concentration, reaction time and temperature on the cadmium removal efficiency were investigated. The samples before and after cadmium removal of sulfureted pyrolusite in different ways were characterized by X-ray powder diffraction and scanning electron microscopy. The results show that the cadmium removal capacity of the products obtained under the conditions of wastewater desulfurization, normal temperature waste gas desulfurization and process gas high-temperature desulfurization are 73.93, 66.76 mg/g and 44.96 mg/g, respectively. The mechanism of removing cadmium from desulfurization products is the dissolution precipitation reaction between MnS and CdS due to the solubility product difference. The difference of crystal structure, morphology and crystallinity of MnS formed by different sulfuration methods is a main reason for its different cadmium removal effect. Pyrolusite desulfurization products have a good removal effect on heavy metal cadmium ions, which can have promising application prospects in environmental pollution control.

软锰矿作为含硫化物废水、废气、沼气、工艺气体等脱硫材料已得到广泛应用,然而其脱硫产物的特性和应用还缺少深入研究。实验模拟废水脱硫、常温废气脱硫、工艺气体高温脱硫工况获得相应的软锰矿硫化产物,探究不同方式硫化软锰矿的物相组成、废水除镉效果及其作用机制。考察了溶液的pH值、初始镉浓度、反应时间、温度等因素对除镉效率的影响,通过X射线粉末衍射、扫描电镜对不同方式硫化软锰矿除镉前后样品进行表征。结果表明,废水脱硫、常温废气脱硫、工艺气体高温脱硫工况获得产物除镉能力分别为73.93、66.76、44.96 mg/g。脱硫产物除镉机理是其中的MnS与CdS在溶度积差推动下发生的溶解-沉淀反应。不同硫化方式导致形成的MnS晶体结构、形态、结晶度差异是其除镉效果不同的主要原因。软锰矿脱硫产物对重金属镉具有良好的去除效果,在环境污染治理中具有广阔的应用前景。

软锰矿作为含硫化物废水、废气、沼气、工艺气体等脱硫材料已得到广泛应用,然而其脱硫产物的特性和应用还缺少深入研究。实验模拟废水脱硫、常温废气脱硫、工艺气体高温脱硫工况获得相应的软锰矿硫化产物,探究不同方式硫化软锰矿的物相组成、废水除镉效果及其作用机制。考察了溶液的pH值、初始镉浓度、反应时间、温度等因素对除镉效率的影响,通过X射线粉末衍射、扫描电镜对不同方式硫化软锰矿除镉前后样品进行表征。结果表明,废水脱硫、常温废气脱硫、工艺气体高温脱硫工况获得产物除镉能力分别为73.93、66.76、44.96 mg/g。脱硫产物除镉机理是其中的MnS与CdS在溶度积差推动下发生的溶解-沉淀反应。不同硫化方式导致形成的MnS晶体结构、形态、结晶度差异是其除镉效果不同的主要原因。软锰矿脱硫产物对重金属镉具有良好的去除效果,在环境污染治理中具有广阔的应用前景。

Pyrolusite is widely used as desulfurization materials for sulfide-containing wastewater, sulfide-containing waste gas, biogas and process gas. However, some studies on the characteristics and applications of its desulfurization products still are lack. This paper simulated the conditions of wastewater desulfurization, normal temperature waste gas desulfurization and high-temperature desulfurization of process gas to obtain the corresponding pyrolusite sulfide products, and investigated the phase composition of sulfureted pyrolusite in different ways and the effect of cadmium removal from wastewater and its mechanism. The effects of solution pH value, initial cadmium concentration, reaction time and temperature on the cadmium removal efficiency were investigated. The samples before and after cadmium removal of sulfureted pyrolusite in different ways were characterized by X-ray powder diffraction and scanning electron microscopy. The results show that the cadmium removal capacity of the products obtained under the conditions of wastewater desulfurization, normal temperature waste gas desulfurization and process gas high-temperature desulfurization are 73.93, 66.76 mg/g and 44.96 mg/g, respectively. The mechanism of removing cadmium from desulfurization products is the dissolution precipitation reaction between MnS and CdS due to the solubility product difference. The difference of crystal structure, morphology and crystallinity of MnS formed by different sulfuration methods is a main reason for its different cadmium removal effect. Pyrolusite desulfurization products have a good removal effect on heavy metal cadmium ions, which can have promising application prospects in environmental pollution control.
