This paper presents a Quantified SWOT (Strengths, Weaknesses, Opportunities and Threats) analytical method and an analytical hierarchy process method which provides more detailed and quantified information on tourism potential in Tuy Hoa city. Quantified SWOT analysis was used to assess the competing strength of Tuy Hoa’s tourism potential with other places. The results of the study presented that Tuy Hoa city has many advantages of beautiful natural landscapes, nature, rivers and mountains. The results of the comparing value of internal and external factors of Tuy Hoa’s tourism potential indicated it under high competitive pressure from neighbor destinations such as Phan Thiet, Hue, Nha Trang and Da Nang. Tuy Hoa’s tourism potential was lower than that of neighbor cities but it has more attractive tourism features.

Macadamia shells were used to prepare modified carbon by chemical agent H2O2 (25%) in 48 hours with coke ratio: H2O2 = 1:10. Modified carbon from Macadamia shells with chemical agent H2O2 has capable of adsorption heavy metal copper (Cu 2+ ) at an assumption concentration is 30ppm in the optimum conditions such as pH = 4, dose is 1.8 g/l, and the processing time is 30 minutes. The result showed that the adsorption ability of the material reached the highest efficiency is 78.33%. This result showed that modified carbon from shells Macadamia by chemical agent H2O2 capable of removing applications on heavy metal copper (Cu2+) in wastewater.

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.

Investigation of Zn2+ heavy metal handling ability by macadamite activated by H3PO4

DOI: 10.37550/tdmu.EJS/2020.01.005
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+.
