Abstract
Description
DTCR | 低分子重金属捕集剂 | |
成分 | 含S与N螯合基的高分子化合物 | 含S与N的低分子有机化合物 |
分子量 | 10~15万 | 100数百 |
重金属去除效果 | 由于与重金属形成强力螯合体,故去除效果优良,尤其对络合盐,也能充分发挥去除效果。处理过的水清澈透明 | 重金属去除效果远不及DTCR。处理过的水略带黄褐色 |
投放量 | 投放量少 | 投放量相当多,才能达到效果 |
含Cd:10ppm的废水1m3的投放量 | 20~30g | 50~180g |
絮凝形成 | 高分子制品,生成絮凝粗大,沉降性好。 | 低分子制品,生成絮凝细小,沉降性差。 |
耐热性 | 良好(200℃稳定) | (150℃) |
低温稳定性 | -20℃寒冷地区也可使用 | 0℃以下生成结晶沉淀,不适宜寒冷地区使用 |
反应终了终了状态 | 立体结构的高分子 | 单一低分子结构 |
