To provide an agent additive amount measurement method which can measure a concentration or concentration equivalent value of dissolved calcium in leaching water and suitably perform removal treatment of the dissolved calcium in the leaching water with an agent additive amount being an appropriate amount.SOLUTION: An agent additive amount measurement method comprises: a reaction step of adding a calcium insolubilizing agent to sampled raw water to immobilize dissolved calcium; a turbidity measurement step of measuring a white turbidness degree of the raw water that has undergone the reaction step; and an appropriate amount additive amount calculation step of calculating an appropriate amount additive amount of the calcium insolubilizing agent on the basis of a turbidity measured in the turbidity measurement step.SELECTED DRAWING: Figure 1 【課題】浸出水の溶存カルシウムの濃度または濃度相当値を測定でき、適量の薬剤添加量で浸出水の溶存カルシウムの除去処理を適切に行なえる薬剤添加量測定方法を提供する。【解決手段】サンプリングされた原水にカルシウム不溶化薬剤を添加して溶存カルシウムを不溶化させる反応工程と、前記反応工程を経た原水の白濁度合いを測定する濁度測定工程と、前記濁度測定工程で測定された濁度に基づいてカルシウム不溶化薬剤の適量添加量を算出する適量添加量算出工程と、を含む。【選択図】図１
