南极洲万达湖湖水上部为氧化环境,铬浓度较低,Cr^(6+)占主导地位,主要以CrO_4^(2-)形式存在;下部为还原环境,铬浓度高,Cr^(3+)为主,以Cr(OH)_2^+和Cr(OH)^(2+)形式存在。湖水中锰、铁的氧化物及氢氧化物颗粒对铬离子的吸附和释放过程,... 南极洲万达湖湖水上部为氧化环境,铬浓度较低,Cr^(6+)占主导地位,主要以CrO_4^(2-)形式存在;下部为还原环境,铬浓度高,Cr^(3+)为主,以Cr(OH)_2^+和Cr(OH)^(2+)形式存在。湖水中锰、铁的氧化物及氢氧化物颗粒对铬离子的吸附和释放过程,控制了湖水铬浓度的变化。 展开更多

Vanda Lake, a typical dimictic CaCl_2 type salt lake, is located in the Wright Valley inAntarctica. Based on the chemical and physical features of the salt lake water, the authorsdiscussed the vertical geochemical distribution of Fe, Mn, Pb, Cr, Cu, Co, Ni, Cd in the lake,and their vertical migration in lake waters, and have tried to set up a model of vertical mi-gration of these trace elements in the water of a closed chloride type salt lake. 展开更多

INTRODUCTIONVanda Lake, located in Wright Valley of Antarctic Trase Mountains, 77 32’S, 161 31’ E, is one of the salt lakes in Antarctica. The lake spreads from east to west, and is bordered by the high rock walls of Asgard and Olympus Mountains on the north and south. The area of the lake is covered by exposed granite with intruded lamprophyre and overlying 展开更多
