[1]上記(ii)により得られた金コロイド濃縮液について、さらに下記の操作を実施。
[2]金のモル数に対して25倍モルとなるように調整した10−カルボキシ−1−デカンチオールを45ml添加する。
[3]1NのNaOHにてpH11に調整する。
[4]16時間攪拌する。
[5]遠心分離(11800rpm,10℃,10分)により上澄み液を除く。
上記方法により、10−カルボキシ−1−デカンチオールで表面修飾した金コロイド濃縮液約1wt%を得た。
図1に示すシステムに対応する実験装置を用い、IPA中に金ナノ粒子を分散させた試料液(原水)をろ過処理し、フィルターの除粒子性能を評価した。すなわち、貯槽10に所定量の原水を貯留し、ここに窒素ガスを圧送して、全量をフィルター18に供給してろ過処理した。そして、原水(S1)を予めサンプリングすると共に、ろ過液をサンプリングした。
