Abstract
【解決手段】本発明は、1又は2以上の金属からなる金属粒子と前記金属粒子に結合する保護剤とからなるコロイド粒子と、前記コロイド粒子の分散媒である溶媒と、を含む金属コロイド溶液であって、金属濃度1質量%あたりの塩化物イオン濃度が25ppm以下であり、かつ、金属濃度1質量%あたりの硝酸イオン濃度が7500ppm以下である金属コロイド溶液である。本発明では、コロイド粒子の保護剤の量を調整することで、その吸着能を向上させることができ、金属粒子の質量に対して保護剤を0.2〜2.5倍結合させたものが好ましい。
【選択図】なし
Description
a.限外濾過:分画分子量10000の限外濾過フィールターに金属コロイド溶液を通過させて塩化物イオンを除去した。
b.遠心分離:金属コロイド溶液に、メタノールを体積基準で10%分添加した後、回転数6000rpmで5分間遠心分離し、上澄みをデカンテーションして取り除き、沈殿物に水を加えてコロイド濃度を調節した。
c.加熱処理:還元剤添加の行う加熱還流処理後(100℃、2時間)に作製した金属コロイド溶液について、そのまま10時間加熱還流処理を行い、硝酸イオンを分解除去した。
d.アルカリ添加:金属コロイド溶液に、pHメータ測定でpHが5〜7になるまでアンモニアを添加した。
