The study aims to investigate the possibility of processing copper metal (Cu2+) with activated carbon prepared from macadamia shell. Activated carbon is prepared from Macadamia shell by chemical agent H3PO4 with coke ratio: H3PO4 = 1:1, optimal temperature condition is 5000C and burning time is 60 minutes. Using the assumed Cu2+ metal treats materials in the laboratory with a concentration of 30ppm. The research to result ability material adsorbed Cu2+ metal achieve good performance 95.92% handle, corresponding to the concentration of Cu2+ reduced from 30 mg/l to 1.2mg/l in optimal conditions is pH = 4.5 , dosage 1.8g/l, time 30 minutes. The results showed that activated carbon prepared from macadamia husk with chemical agent H3PO4 was capable of treating copper metal in wastewater.
Investigation of the possibility of treating wastewater containing Cu2+ heavy metal with activated carbon material prepared from macadamia husk with activating K2CO3 in Optimal conditions such as temperature 6500C and burning time is 60 minutes. Survey results show that coal with the ability to handle heavy metals is best at 84.02% in optimal conditions such as pH=5 and time. Baking is 30 minutes. The results show similarities with other research results and are applicable to wastewater treatment Cu2+.

Seed coat macadamia preparation of activated carbon with chemical agent K2CO3 from macadamia shells as per ratio: K2CO3: distilled water = 1:1:10ml, optimal temperature condition 6500C and burning time 60 minutes. Efficiency removal of zinc (II) in wastewater efficiency (53.42%) with the concentration of 25ppm, conducted a survey at pH = 4.5 with 1.8g/l of carbon, treated in 100 minutes. Survey results have similarities with other studies and are applicable to application removal of zinc (II) in wastewater.

Methylene orange handling of cock cake casted by H3PO4 chemicals

Survey of methylene orange wastewater treatment by activated carbon material prepared from macadamia husk with chemical activator H3PO4 shows that coal with the best methylene orange color treatment is achieved Optimal conditions such as pH = 5, coal dose 0.9 g/L and time 120 minutes. The results show that it is applicable to color wastewater treatment and the results are similar to other research results.
Investigate the possibility of treating wastewater containing heavy metals Zn2+ with activated carbon material prepared from macadamia shell with chemical activating agent H3PO4, showing high efficiency of adsorption of Zn2+. The results of the study showed that activated carbon with H3PO4 activating agent has high adsorption capacity, capable of handling Zn2+ best at pH = 4.5, dosage 1.8 g/L and time is 120 minutes. . The results show similarities with other research results and are capable of treating wastewater containing heavy metals Zn2+.
