calcium chloride

With calcium chloride precipitant to eliminate the interference of PO43-, total nitrogen in compound fertilizer is determined by formol method.

用氯化钙作沉淀剂，消除磷酸根离子的干扰，用甲醛法测肥中的总氮。

Aluminum sulfate, calcium chloride and lime are taken as raw materials.The products have high flocculability because of the existing of sulfate ion .

该工艺以酸铝、铝化钙和石灰为,入酸根离子,产品的絮凝性能大大提高。
