《Leaching Effect of Organic Acids on Heavy Metal Contaminated Soil》
The p H and conductivity of the soil sample filtrate after the first water washing was determined using a p H meter with a composite glass electrode and a DDP-210 portable conductivity meter（Table 1）.As shown in Table 1，the p H of soil samples without lime water treatment was mostly in the range of 3.3 to 3.6，all smaller than 4.5（the critical value for maintaining crop growth）[19]，which was unable to maintain the growth of crops.
