摘要
研究了直接氧化法制备聚合硫酸铁过程中产品盐基度的影响因素 .结果表明pH值、加料方式、反应温度、反应时间、原料浓度、助聚剂、存放时间等均会影响盐基度 .在pH为 1 .3时 ,原料液中绿矾的质量为 1 6.89% ,氧化剂配成溶液一次加入 ,并加入绿矾质量的 0 .6%左右的助聚剂 ,在 3 0℃下反应 2h以上 ,产品存放 2 4h后可使盐基度稳定在 2 0
In this paper ,the major factors effecting the alklization degree of polymerized ferric sulphate in its preparation process by direct oxidizing method were investigated. Experimental results showed that such as pH value, charging ratio and method, reaction temperature and reaction time, concentration of material, assistflocculant and resting period can all influnce the alkalization degree of product. Under suitable conditions: the oxidizing agent by aqueous solution is added in system at one time, the pH is 1.3, the concentration of material (the mass percent of ferrous sulfate) is 16.89%, the reaction temperature is 30℃, the reaction time is 2h, about 0.6% of quantity of ferrous sulfates assistflocculant is added in them ,at last the alkalization degree of product can be stabilized above 20% after the product is lefted for 24h.\;
